Being able to win the National Highest Technology Award made Ye Chen very happy.
The awards were given on January 10th. With less than half a month left, Ye Chen decided to take his family to Huangchenggen to travel. By the way, visit Zeng Guoming to see if I can operate on my father.
At the same time, Ye Chen decided to reward the outstanding employees, and the company paid for them to take them to Huangchenggen. If you have the opportunity, you can have the best employees attend the awards ceremony.
Ye Chen immediately summoned the senior executives of these companies, Xiao Lingyue, to agree with them. Although the company has not been established for a long time, the prospect is very good. So far, very good achievements have been made. This is not only the efforts of Ye Chen, but also the efforts of all employees, and the efforts of outstanding employees. Therefore, it is necessary to reward these outstanding employees.
It was a big event to win the National Highest Technology Award. The news spread quickly like the wind. Secretary Gao and Mayor Tao rushed to see Ye Chen's proposal that Fengzhou would hold a celebration party for Ye Chen.
Fengzhou is a second-tier city in the southwestern province. If put into the whole country, it would look like a third-tier city. Ye Chen won the highest national science and technology award. This is a big thing for Fengzhou. You can make good use of this to enhance the reputation of Fengzhou. This is a big thing for Fengzhou. benefit.
Ye Chen still refused. This kind of thing just needs to be lively. There is no need to have a special scene or a celebration party, which is inconsistent with Ye Chen's idea.
As for the promotion of Fengzhou's reputation, isn't Ye Chen putting the company in Fengzhou enough to raise Fengzhou's reputation? If you go online to see, the whole world knows the concept technology of the future, and the whole world knows Fengzhou. Is this famous enough?
Regarding Ye Chen's choice, Secretary Gao and Mayor Tao had no choice but to respect them.
Zhuang Lao greatly appreciated Ye Chen's choice and was very pleased. This kind of thing, if changing the individual, the possibility of holding a celebration party is very high, but Ye Chen rejects it, and this mentality is very good.
That night, the city's leaders and company employees, as well as Ye Chen's family, gathered in the company cafeteria and held a celebration party. Everyone got together, talked and laughed, and had a good meal. Ye Chen won the award and celebrated the event Even if it's done.
My mom and dad also supported the trip to Huangchenggen, especially my younger brother Ye Xiaohua bounced and couldn't sleep anymore. I ca n’t wait to visit Huangchenggen immediately.
Before going to bed at night, Ye Chen opened the system and looked at it, and it has millions of contributions. After another day or two, the lottery can be drawn again. What should I do this time?
Up to now, Ye Chen has learned a lot. The technologies provided by the system are not independent, but complement each other. Each technology needs other technological support.
After thinking for a while, Ye Chen decided to choose information technology.
Modern society is also called the era of information explosion. Since the existence of network satellites, the earth has become a "global village". What happened on the other side of the earth, this side of the earth will soon know, and even live broadcast.
This is all because of information technology. Without advanced information technology, this situation would not have happened.
Therefore, Ye Chen chose information technology. Ye Chen is looking forward to it, and information technology can surprise him.
The next day, Ye Chen officially began to verify the laser material technology. Ye Chen wanted to do this early, just because he wanted to help the chief teacher to make a full-authority digital photon control system.
Until now, the orders and intent orders received by Ye Chen have exceeded the three trillion mark. This requires a lot of laser materials, which has far exceeded the military's supply capacity. Therefore, Ye Chen must verify the laser material technology as soon as possible and build a factory as soon as possible.
In the 20th century, human beings had many great inventions, such as atomic energy, computers and semiconductors, and lasers. It is these great inventions that have promoted the tremendous progress of human society and benefited all mankind.
The laser, originally called "stimulated radiation amplification," was later changed to "laser" according to the proposal of the father of the missile. This term has been used until now.
There are four main advantages of lasers: one is high brightness. The laser has a strong emission ability and a high concentration of energy, so the brightness is very high, billions of times higher than that of ordinary light sources, and tens of billions of times higher than the brightness of the sun's surface.
Brightness is an important indicator for measuring the quality of a light source. If a medium-intensity laser beam is converged, it can generate a high temperature of several thousands to tens of thousands of degrees at the focus.
The second is good directionality. After the laser is emitted, the divergence angle is very small. The laser emits 20 kilometers and the spot diameter is only 20 ~ 30 cm. The laser reaches 380,000 kilometers on the moon, and the spot diameter is less than 2 kilometers.
If the moon is illuminated with a searchlight beam, it will be enough to cover the entire moon when it reaches the moon. This shows how good the directivity of the laser is.
The third is good monochrome. The color of light is determined by the different wavelengths of light. Different colors are reflected by the different effects of light of different wavelengths on human vision. The wavelength of the laser is basically the same, the spectral line width is very narrow, the color is very pure, and the monochromaticity is very good.
Because of this characteristic, lasers are widely used in communication technology.
Fourth, the coherence is good. Coherence is the commonality of all waves, but because of the different qualities of various light waves, their coherence is also different.
Ordinary light is spontaneous radiation and does not cause interference. Laser is different from ordinary light source. It is stimulated radiation and has strong coherence, so it is called coherent light.
It is precisely because of these characteristics that lasers have a wide range of applications that are indispensable for civilian military applications. Civilian direction, such as steel cutting and medical treatment.
The military aspect is even better, and various laser weapons are emerging endlessly, making people talk about it.
The theoretical basis of laser light comes from Einstein, who is always different from ordinary people. He proposed in 1917 that "light interacts with matter."
This theory is that among the atoms that make up matter, different numbers of particles are distributed at different energy levels. Particles at high energy levels are excited by certain photons and will transition from high energy levels to low energy levels. It will radiate light with the same properties as the light that excites it, and in a certain state, a phenomenon that a weak light excites a strong light can occur.
This is called "light amplification of stimulated radiation", and our country is called laser for short, according to the proposal of the father of missiles.
To achieve this theory, scientists have been working hard for decades. By May 1960, American scientists had finally completed the world's first laser and produced the first laser in human history.
In September 1961, our country manufactured the first laser in our country, which was only a little later than the United States. You know, the strength of our country at that time was really weak, and the level of scientific research was not good enough, and it was far from being comparable to that of the United States.
Even under such difficult conditions, it is amazing that our country can still manufacture lasers after the United States.
Later, with the efforts of scientists in our country, our country has made major breakthroughs in laser crystal materials. Due to the need for confidentiality in the national defense, no announcement was made, making the three scientists miss the opportunity to win the Nobel Prize.
Therefore, there is a rumor in the world that if our country's laser technology was announced, it would have won the Nobel Prize 30 years ago.
Later Russian scientists won the Nobel Prize for major breakthroughs in laser materials, which is later than our country's achievements. It is said that there is a big gap in performance.
Although our country has missed the Nobel Prize, it is this major breakthrough that has made our country's laser technology a good achievement and is a world leader in many aspects. It is the United States that has been putting pressure on our country and wants our country to lift restrictions on the export of laser materials.
There are many materials that can be used for lasers, both gas and liquid, and the most promising now is crystalline materials. Ye Chen is verifying crystal materials. The technology he masters is simple to manufacture crystal materials, low cost and high yield.
The current production of laser crystal materials is not high, the cost is higher, and the technology is difficult. Although countries are investing heavily in research, often only samples are obtained, and not many can be used for actual production.
For three days, Ye Chen stayed in the laboratory for verification. At first, Ye Chen failed several times due to his lack of experience. Later, with the accumulation of experience, he became more and more smooth and made great progress.
Three days later, Ye Chen knew that he didn't have any prospects in the laser material, so he could stop there.
After these three days of hard work, Ye Chen not only verified the laser material technology, but also wrote the production process. You can build a factory. Ye Chen believes that as soon as his laser materials come out, the laser materials on the market have to stand aside.
According to Ye Chen, the best laser material on the market is the laser material in our country, and the laser materials in other countries have very poor performance.
Although the laser material in our country has good performance, it has insufficient capacity and high cost. This is far from meeting the needs of Ye Chen. Now that Ye Chen has mastered laser technology, this problem has been solved, and our country will be in a more advantageous position in the field of laser technology.
Before building the factory, there is one more thing to do, and that is to apply for a patent.
Like last time, Ye Chen filled out the information on the official website of the Patent Office, paid the handling fee, and waited for the patent office to review it.
The last time I applied for a patent, there was such a big storm, and the photonic chip technology was almost snatched away. Ye Chen thought that no one would it again this time, right?
After filling out the information, Ye Chen packed for a while, ready to go out to rest. Seeing that New Year's Day is coming, the company has some New Year's activities. The chairman of this company must not participate, it is time to help.
Before he left the laboratory, the phone rang. Ye Chen took a look. It was Liu Zhilong, director of the State Patent Office.
Ye Chenxin said, what's up with him? After being connected, Ye Chen had not spoken yet, so he listened to Liu Zhilong shouted, "Xiaoye, what do you call me, how do you do?"
Ye Chen stunned, what do you mean?
