Chapter 3 Improved Laser

"How is it, son? Isn't this handmade laser device from Dad pretty good?"

At this moment, Lin Weiliang squatted down beside him and said, "Let me tell you, this laser device is a device that turns electricity into laser light."

It's different from the fluorescent lights we usually see; the beam is purer and the energy is stronger..."

Lin Dong rolled his eyes inwardly as he listened to his father's explanation.

Natural science courses are only offered in the third grade.

You're talking to an eight-year-old second grader about electricity turning into light, fluorescent lights, and energy... Dad, if you don't know how to teach, then don't teach.

If it were a typical child, you'd be ready to answer a million "whys" right now.

Lin Dong mentally scoffed for a moment, but didn't expose Lin Weiliang's self-praise. He raised his head and said...

"Dad, I want more books about laser devices."

"What do you need so many books for?"

Lin Weiliang was puzzled, not even considering that Lin Dong had finished reading and understanding the book in such a short time.

"Mother!"

But to his surprise, Lin Dong didn't explain at all, and instead turned to look towards the kitchen: "Dad won't let me read!"

"Lin Weiliang!"

As soon as Lin Dong finished speaking, a loud roar erupted from the kitchen.

"Hey, hey, I didn't say I wouldn't let him see it..."

Lin Weiliang was stunned for a moment, then hurriedly stood up and said, "Here, it's all yours!"

talking.

Lin Weiliang took out several books and some collected and printed documents from the bookshelf and placed them in front of Lin Dong with a solemn expression.

"It's settled then, you can look and play, but you can't scribble or tear the books, otherwise Mom will protect you, but Dad will beat you."

"Okay, Dad, you're so long-winded."

Lin Dong muttered something, then opened the first book and began to read it seriously.

"The core of a laser is an amplifier. The pump source generates a light beam that enters the amplifier. The high-energy medium of the amplifier itself transitions to a low-energy state under the illumination of the light beam, releasing an identical photon."

"As long as the amplifier remains in a high-energy state, the number of photons can increase exponentially, rapidly growing from a weak seed beam into a powerful laser..."

"A powerful and stable amplifier is key to all laser weapons."

Lin Dong carefully studied the knowledge in the book.

With his soul-seeing vision, he can remember books after reading them once and understand knowledge at a glance. This timely positive feedback keeps him engaged at all times.

As his understanding of lasers deepened, a new laser design began to emerge in his mind...

"Xiao Dong, dinner's ready."

After some time, Zhang Xiali came out of the kitchen carrying a plate of scrambled eggs with tomatoes and a plate of spicy tofu with minced meat. Then she went back and brought out a plate of Kung Pao chicken and a plate of stir-fried vegetables.

"Weiliang, take Xiaodong to wash his hands and get ready for dinner."

"I can wash myself."

Lin Dong snapped out of his reverie, answered, closed his book, and went to the balcony alone to wash his hands.

"That's great! I didn't have to ask my parents to help me today."

When Lin Dong finished washing his hands and returned to the dining table, Zhang Xiali gave him a thumbs up.

talking.

Zhang Xiali served Lin Dong half a bowl of rice, then added some vegetables, and placed it in front of Lin Dong along with children's chopsticks.

After being reborn, Lin Dong no longer dawdles for half an hour while eating, unlike before.

He finished his meal in less than twenty minutes and once again received a round of applause from Zhang Xiali.

After the family finished dinner and rested for a while, Lin Weiliang took charge of cleaning up the dishes.

Zhang Xiali went to the bathroom to prepare the bathwater and then urged Lin Dong to take a bath.

After taking a shower and drying her hair, it was almost nine o'clock. Zhang Xiali tidied up the bed in the small room and then told Lin Dong to go to sleep.

September in Chengdu.

Summer is still in full swing, and mosquitoes remain unusually active.

Zhang Xiali pulled up the mosquito net, swatted away two mosquitoes that had escaped, adjusted the air conditioner temperature, and looked at Lin Dong, who was already lying obediently under the thin blanket. She seemed to have thought of something and gently instructed him.

"We got back from the hospital quite late today, so it's bedtime now and we can't watch cartoons."

But when you get home from school tomorrow, you can watch two more episodes on Dad's computer.

Lin Dong blinked: "Mom, can I play on the computer instead of watching cartoons?"

"Playing computer games?"

Zhang Xiali paused for a moment, then nodded at Lin Dong's expectant eyes: "Then I'll have Dad set up a separate account for you on the computer tomorrow."

"If you want to play, log in to your account. Don't touch Dad's things."

"Okay, I won't touch your things."

Lin Dong nodded obediently, closed his eyes, and said, "Goodnight, Mom."

"Okay, goodnight, Xiaodong."

Zhang Xiali patted Lin Dong's head, checked again to make sure there were no mosquitoes inside the mosquito net, turned off the light, and left Lin Dong's room.

The next day.

At seven o'clock in the morning, Lin Dong was woken up by Zhang Xiali. After brushing his teeth and eating breakfast, he went to school.

On the way to school, sunlight filtered through the leaves of the plane trees, casting dappled patterns on the ground.

Lin Dong held his mother's hand and walked forward. Just as they stepped out of the community gate, they ran into Xu Qingling's family.

Xu Qingling's father, Xu Ziming, was wearing the uniform of a senior technician at Chengdu Aircraft Industry Group, while her mother, Zhou Xiaoyan, was carrying Xu Qingling's small schoolbag.

Upon seeing Lin Dong's family, the two quickened their pace and walked over.

"Good morning, Engineer Lin and Engineer Zhang."

Xu Ziming greeted him with a smile, his gaze falling on Lin Dong: "I heard Xiao Dong fainted at school yesterday, how is he now?"

"It's nothing serious, he woke up shortly after arriving at the hospital."

Zhang Xiali smiled and said, "The doctor checked my CT scan and EEG, and everything was fine. He just told me to rest more and not overwork myself."

"That's good, that's good."

Zhou Xiaoyan breathed a sigh of relief upon hearing this: "We were quite worried yesterday when Qingling told us about it."

Xu Qingling then let go of her mother's hand, walked up to Lin Dong, and blinked her big eyes, asking, "Lin Dong, what did you do at home last night?"

Lin Dong looked at the crybaby, then glanced at Xu Ziming, a senior technician from Chengdu Aircraft Industry Group, behind her. After thinking for a moment, he said, "Reading. I'm preparing to make a laser device."

"Wow!"

Xu Qingling's eyes lit up instantly, and she exclaimed with admiration, "Is it that kind of laser that makes 'biubiubiu' sounds?!"

Her voice was clear and loud, which made the adults on both sides laugh.

"Yes, that kind of laser."

Lin Dong nodded, looking at Xu Qingling's adoring expression, and felt a strange urge to laugh.

Who would have thought that Xu Qingling, who stood in the spotlight on the world e-sports stage in her previous life, was such a little fangirl who would shout "Wow" at the drop of a hat during her elementary school years?

Xu Qingling became even more excited upon receiving confirmation, and took a step closer, saying, "I played Contra at home last night!"

Let me tell you, my dad's really bad at video games. He can't even beat Contra in one life, and he can't even beat the third boss. I have to go and save him!

"Cough cough..."

Xu Ziming coughed awkwardly twice, "Qingling, there's no need to say anything about this..."

"Why don't you say so?"

Xu Qingling turned around, her face full of confusion and self-righteousness, and said, "Dad, you're really bad at video games. Mom also said that you can't even beat your daughter in video games."

Zhou Xiaoyan couldn't help but laugh and turned her face away to chuckle.

Lin Weiliang and Zhang Xiali were also all smiles; the scene was just too funny.

Xu Qingling turned her head and continued sharing with Lin Dong: "Yesterday I played Super Mario, Battle City, and Adventure Island. Super Mario just released a new version recently..."

The little girl laughed as she talked, her smile pure and radiant, like the cleanest ray of sunshine in the morning.

As Lin Dong listened to Xu Qingling chattering away about her gaming experiences, and looked at his childhood sweetheart from decades ago, a smile involuntarily crept onto his lips.

Upon rebirth, his soul consciousness remained in a state of overlooking from a higher dimension.

Although the mind becomes incredibly powerful, as the soul's vision is enhanced and the body's instinctive desires are controlled, there is always a sense of alienation from the world.

Listening to the little girl's innocent laughter, I couldn't help but feel a bit more childlike myself. My slightly tired mind, which had been tiring from reading several books last night, suddenly felt much more relaxed.

"Lin Dong".

Xu Qingling suddenly stopped laughing and looked at him seriously: "When your laser device is finished, can I take a look at it?"

"Can."

Lin Dong nodded, paused, and then added, "But you can't look them in the eye."

"Mmm!" Xu Qingling nodded vigorously, her eyes full of anticipation.

Throughout the journey, Xu Qingling chattered away like a happy little sparrow.

One minute she's asking what noodles she ate for breakfast, the next she's asking what games Lin Dong usually plays; her train of thought jumps around so much it's hard to keep up.

Lin Dong responded casually, but didn't seem annoyed.

Soon, the two arrived at the school and entered the classroom amidst their parents' instructions.

Another day of elementary school life was spent in noise and commotion.

Zhang Zihua continued his antics, Li Tao lived up to his nickname "King of Shit" by calling to go to the toilet twice that morning, and Zhang Yihao was still his little tyrant, bullying his classmates everywhere after class.

Xu Qingling was much quieter, occasionally stealing a glance at Lin Dong, lost in thought.

Lin Dong lay on the table, watching his classmates make a ruckus while mentally refining his laser device design.

Time passed quickly amidst the noise.

At 4 p.m., school let out, and Lin Dong waited at the after-school care center until after 5 p.m.

Zhang Xiali appeared at the classroom door carrying some fresh vegetables and picked up Lin Dong to go home.

"Mom, where's Dad?"

Lin Dong looked around but couldn't find Lin Weiliang.

"Dad has to work overtime today, he'll probably be home a little late."

Zhang Xiali, adhering to the principle of confidentiality, did not reveal too much. She picked up Lin Dong's schoolbag, took his little hand, and walked out.

"oh."

Lin Dong nodded without saying anything more.

As a military industrial enterprise, Chengdu Aircraft Industry Group (CAC) employees are sometimes like this, working day and night when they get busy. He was used to it in his previous life.

Back home, Zhang Xiali changed her clothes and went into the kitchen to prepare dinner for the family.

Since Lin Dong turned one year old and they can eat together, Zhang Xiali cooks for him whenever she has time, and changes the menu regularly to try to make sure he eats healthier.

Lin Dong watched his mother's busy figure, but instead of going to the living room to watch TV, he went to the storage area on the enclosed small balcony, where he found the laser devices that had been disassembled yesterday, and picked out some electronic components and optical lenses.

"Laser generator, resonant amplifier, power capacitor module, cluster lens, heat dissipation module..."

Lin Dong carefully checked the components he had selected, closed his eyes and entered a state of spiritual vision, then focused his mind on the components in front of him.

call!

In an instant, the whole world was transformed.

The structure, function, defects, and optimization directions of every device in front of him all emerged in Lin Dong's mind as a perception that transcended language.

"The original design of the resonant amplifier was not optimized enough, and the high-energy state was not maintained for long enough, which limited the amplification power."

"The laser angle entering the amplifier is also not good, which reduces the number of times the laser can be repeatedly excited and amplified, resulting in the amplifier's efficiency being only 23 percent."

"The original coating on the focusing lens was damaged, which caused distortion and phase issues in the laser beam, making it unable to effectively focus the beam..."

Lin Dong opened his eyes, picked up the screwdriver and soldering iron next to him, and began to improve and assemble.

The capacitors in the power module were replaced with more stable tantalum capacitors, and other resistors were also replaced accordingly.

The pump source of the resonant amplifier was re-adjusted at the incident angle, and a larger amplifier was replaced.

The cluster lens group uses six brand-new coated lenses, reassembled into a new lens group.

The heat dissipation module has been redesigned with a new fin arrangement, and air ducts and a miniature fan have been added to make air convection smoother.

Every change was based on the laser device books and literature I studied last night.

Every adjustment is based on the optimal judgment under the direct blessing of the soul.

Half an hour passed quickly.

The various parts in front of Lin Dong had disappeared, replaced by a rough-looking laser with some components exposed.
