Siheyuan: Starting from a fitter

Chapter 302 Laser Interferometer
In the next few days, Li Guocheng inspected various laboratories and the progress was smooth.

Two important projects he has focused on are helicopters and laser technology.

When designing drones and robots, he will definitely pay attention to the progress of these two projects every week, and will help solve problems in time when encountering them.

China manufactured the first laser in 1961, only one year later than the world's first laser, which shows that China has accumulated a lot in laser technology.

Since then, China has never lagged behind others in laser technology, and is far ahead in some areas.

The main research direction of the laser laboratory in the Kyoto laboratory is the design of DUV light sources and laser interference ranging.Li Guocheng has prepared a lot of information in this area.

Most of the information comes from Hughes Aircraft Company, and the other part is Li Guocheng's own understanding and deduction.

Today, Li Guocheng came to the laser laboratory.

"Dong Li, you are here at the right time. We have imitated the gallium arsenide laser source and designed the lens group for laser interference distance measurement. Next, we need your help for photoelectric reception and data processing."

After Professor Yuan saw Li Guocheng, he reported happily.

"Great, let me take a look first."

Professor Yuan directed the students to give Li Guocheng a demonstration. Through the color palette, you can see the interference fringes of light and dark.

"It's very good. I'll be in charge of the receiver. The finish of the beam splitter and reflector can be improved a little. Leave this to me as well."

Half a day later, Li Guocheng handed over the 5 sets of beam splitters and reflectors to Professor Yuan, then hurried back to the 6th floor and started designing the photoelectric receiving module.

With the information from Hughes Company, multiple experiments and optimizations, in less than a month, Li Guocheng designed a photoelectric receiving chip with a theoretical accuracy of 10 ppm and a resolution of up to 10 nanometers.

Taking the mask, he handed it to Yan Jiefang on the fifth floor. In just two days, Li Guocheng got 5 optoelectronic chips.

Another half month passed, and the first laser interferometer rangefinder officially appeared at the Longhua Research Institute in Kyoto.

"Dong Li, it has been repeatedly verified that the measurement accuracy is 10 ppm and the resolution is 12 nanometers."

Professor Yuan held the data sheet with tears in his eyes, because this was a historic breakthrough. From then on, China also had its own high-precision laser interferometer.

Its practical significance cannot be overestimated no matter how high it is, which laid a solid foundation for China to enter precision machining.

"I am proud of your team. As a reward, Longhua Technology is prepared to reward your laboratory with 100 million yuan."

The few people who were cheering seemed to have pressed the pause button, and the cheers stopped abruptly.

Soon there were louder cheers.

Professor Yuan heard that the 100W reward did not fluctuate much, but felt it was a bit much, but he was still very happy.

His performance was keenly captured by Li Guocheng.

"Everyone, this 100 million reward must be earmarked for special use. I will inform the finance department that this money can only be used for laboratory construction, including your daily expenses.

Such as round-trip tickets, meal allowances, taxi fares, and various activity funds.

At the same time, Professor Yuan will be awarded 1 yuan personally, and none of your students will be awarded [-] yuan.

Then I will reward each of you with a [-]-inch large color TV."

Li Guocheng's additional reward directly made the laboratory fry.They are also people and family members, and the primary purpose of reading is to change their destiny.

Now that the reform and opening up has begun, and with overwhelming reports, everyone is slowly getting to know Western developed societies and the country of Sam, and everyone has never had such expectations for a better life.

So cash and color TV are the biggest rewards for them, and I want to tell everyone that as long as you work hard and make achievements, you and your family can live a good life.

With the laser interferometer, he can manufacture some precision instruments, and the conditions are also met for the mass production of semiconductor gyroscopes.

"Professor Yuan, please continue your efforts and break through the DUV light source first, and then consider laser cutting and drilling, which can improve the processing accuracy of our industry."

"Don't worry, now that the information is so complete and there is no shortage of experimental materials, a breakthrough is only a matter of time. However, we are currently short of manpower, and we may have to transfer a few more people from the school."

"There are no problems. I'll let Bai Yu solve life problems. If you can't solve other problems, just come to me."

"That's a good thing."

"I have to trouble you to build a few more units. One is to provide them to semiconductor laboratories, and the other is to declare them to the state."

"Don't worry, the remaining materials can make more than [-] units. If not, we will prepare new materials."

"enough".

A few days later, Chinese official media reported this great news, and the whole country was excited.

Longhua Technology once again entered the attention of the Chinese people.This time it’s not about electrical appliances or donations, but it’s about high technology.

Several media invitations came one after another, but Li Guocheng refused them all.

Some scientific research institutes applied for study tours, but were rejected due to the special nature of the laboratories.

The public is full of praise, but in the eyes of some people, Longhua Technology is given the title of arrogance.

Time passed in such a hurry.

In a certain office, several soldiers reported their work to the old man sitting in the chair, including Representative Luo and Political Commissar Tian.

"Chief, through our investigation, Comrade Li Guocheng is actually not from Xiangjiang, nor a Malay, nor a Sam, but an out-and-out Chinese.

Jackie Chan is just a pseudonym for him in Xiangjiang. He is an authentic Kyoto native.

Why he left Kyoto has been reported just now. Now let me talk about what interests you.

His true identity is a semiconductor expert, computer expert, drone expert, aircraft turbine engine expert, and he invented even the individual cloud explosive bomb."

"What? You said he invented the individual soldier cloud bomb. Wasn't he in Xiangjiang at that time?" the leader asked doubtfully.

"After he went to Xiangjiang, he would send scientific research results back to China every year. Many of the results of the National Semiconductor Research Institute were sent back by him.

Moreover, his time in Xiangjiang did not delay him from starting a company. In just [-] years, Longhua Technology, which he founded, has become a world-renowned high-tech enterprise.

After the reform and opening up, he began to invest heavily in my country. First, he donated HK$[-] million to Shekou to help the local government build an industrial zone.More than [-] billion yuan has been invested in Shekou.

Establish factories and research institutes to produce high-quality electrical appliance production lines and Longhua brand home appliances."

“What a wonderful man, he has never stopped making contributions to the country in the face of setbacks.

Especially individual weapons, changed that war.Today's drones will cause another military revolution.

His wild ideas are the scariest and most precious.We have to protect him."

"This is what I have always been curious about. It is said that such a person has long been known to the world. If we did not have sufficient authority, then he would be an ordinary person in front of us.

It seemed that someone was silently protecting him, the most likely being Mr. Zhao.Because when he was emerging, he encountered many assassinations by foreign forces."

"That should be the case. Being low-key is also a form of protection."

"There is one more thing, I don't know whether I should talk about it or not?"

"put".

"Hey! There seems to be something fishy about his departure back then. It seems that he was targeted or framed."

"It's just playing the piano randomly", the chief got angry for the first time.

Staff Officer Tian shrank his neck. After achieving his goal, he became a little turtle.

After a while, the chief sighed and his mood slowly stabilized, "Spread the word, he is the person our military wants to protect."
