Chapter 1052

Some people may say that LBO crystal can double the frequency of laser to 355 nm, which is not much different from 176 nm. As long as several groups of lens crystals are added, the laser wavelength can also be compressed to 170 nm.

In theory, however, let alone the 170 nm range, as long as the method is appropriate, even a water drop can compress the laser wavelength to less than 100 nm.

However, the problem is that even if such lasers are compressed to the extreme, their energy will not increase. There is no way. How to compress them is only in the ultraviolet region, and their energy is naturally limited.

If we want to compress the laser wavelength and increase the energy density, we can only use the deep ultraviolet region or the extreme ultraviolet region.

However, solid crystal laser components have a natural defect, that is, they can't enter the deep ultraviolet region below 200 nm, so they can't get high-energy laser.

KBBF crystal just solves this problem, using the unique nonlinear crystal structure of coupling optical materials, we successfully obtain 176 nm deep UV high-energy laser body.

On this basis, the high-energy laser equipped with KBBF crystal can carry out targeted high-energy damage to the damaged satellites 40 km to 80 km away from the ground according to the guidance of the space TT & C station, so as to avoid the generation of space garbage or stop the falling of the damaged spacecraft, and avoid the loss of people and property on the ground.

As for the air force's hope to install this set of equipment on the Il-76 large transport aircraft to build an air laser platform, and the Navy's hope to transplant it to warships to build sea-based interception devices, that's the end of the story. Anyway, the relevant projects have begun to prepare, and Tengfei group has started the pre research in this aspect.

In addition to military applications, KBBF crystal is also widely used in industry. For example, the next generation of 3D printing equipment being developed by Tengfei group uses KBBF crystal as its core laser components. For another example, the new generation of laser precision welding robot of Tengfei group also uses KBBF crystal.

There is also the first generation of domestic deep UV lithography machine developed by Tengfei group and whnb semiconductor, in which KBBF crystal is the core component of laser etching equipment.

For this reason, Luan Heping, one of the founders, chairman and co CEO of whnb semiconductor, almost didn't take Tengfei group as his home during this period of time. He almost ate and drank in Tengfei group, just to keep an eye on the progress of domestic deep UV lithography.

The reason for this is very simple. Once the domestic deep UV lithography machine with KBBF crystal is put into mass production and put into application, whnb semiconductor will be able to make 193 nm chips into cabbage price directly, so as to expand the market share and fully embrace the low-end chip manufacturing.

It can be said that the domestic deep UV lithography machine of Tengfei group is the key link for Luan Heping's whnb semiconductors to leap from the low end to the middle end.

It is the killer of the headquarters, the tactical weapon system of the Navy and air force, the key manufacturing equipment of aerospace, and the key of the semiconductor industry.

Since its birth, KBBF crystal has become the key to upgrade domestic industries in various fields.

The problem is that KBBF crystal is not the potato in the farmer's field. After all, it is a high-tech optical material, which is not easy to prepare.

Up to now, it can not be mass-produced, only small-scale preparation can be carried out in the laboratory.

However, Professor Chen, now the vice president of Tengfei group's Institute of rigid science, has started the research in this field, and it is expected that a set of reasonable large-scale industrial preparation scheme will be given in the next two to three years.

Speaking of Professor Chen, he is also a strange person. He used to be the master's tutor of Hu Rongyi, a senior researcher of Optics Research Institute of Tengfei group.

After taking Hu Rongyi's class of students, Professor Chen was transferred to Fujian Province as a researcher of Fujian Institute of physics. In the early 1990s, Fujian Institute of physics responded to the call of reform and began to establish its own entity business unit, adopting the market-oriented principle to manage scientific and technological achievements.

At that time, the Institute hoped to operate six listed companies in five to eight years, which could improve the treatment of medical researchers and solve the problem of insufficient research funds.

Among them is the research group of laser solid state devices led by Professor Chen.

The problem is that it was very difficult to audit the listing at that time. Apart from that, all provinces basically gave the indicators to those state-owned enterprises with good industrial prospects but very difficult at present, in order that these enterprises could tide over the difficulties through listing and financing.

As a result, the listing process of Professor Chen's research group is far away, so he, like the leaders of other research groups, exerts pressure on the Institute while crossing the sea, showing his magic power and running around.

Professor Chen didn't know where he heard that his student Hu Rongyi had a good development in Tengfei group, and he was able to talk to the top management of Tengfei group.

In the early 1990s, although there were some problems in the development of Tengfei group, it was much better than most enterprises. What's more, Tengfei group had a strong profitability and was a major shareholder of China Merchants Bank. China Merchants Bank controlled many enterprises in the special economic zone and Hong Kong Island, including whnb semiconductor and civil aviation Reform on behalf of Qiongdao airlines, so mixed together, Tengfei group is simply a giant in the capital giant.Definitely a sneeze can make the Shanghai and Shenzhen stock markets tremble.

In addition, during that period of time, Tengfei group and the management came and went. In the end, the management changed a lot, and the joint venture company of Tengfei group and several aviation manufacturers successfully landed in the Hong Kong stock market.

What's more, it makes the outside world think that behind Zhuang Jianye, the leader of Tengfei group, there is a big backing. As long as Zhuang Jianye says something, all the indicators and plans are green.

It is such a rumor that Professor Chen wants to try his luck with his students.

A few years ago, Professor Chen, who was full of old-fashioned intellectual ideas, could not let go of his face. The problem is that he did not think for himself, but also for a group of technicians.

You know, many people have been doing research on nonlinear crystal optical components with him since the 1970s. For more than 20 years, they have been biting their teeth and sticking to it. Now they can finally see the results and change their lives with knowledge. They can't get stuck here because of the difficulties in examination and approval.

So Professor Chen thought for two days and nights, studied countless kinds of words, and finally got on the train to Hebei Province in a hurry to find his students.

At that time, Tengfei group encountered unprecedented difficulties in the field of high-energy laser. At that time, Tengfei group did not think about solid-state laser components, but gas laser was still the mainstream route of high-energy laser in the world at that time, even in the United States. Their main KDP crystal was only used as tactical laser weapon components, such as deep ultraviolet and extreme ultraviolet Some high-energy lasers can only be realized by gas or liquid lasers.

The problem is that no matter liquid or gas, let alone Tengfei group, there is no good thing that can be held in the whole country. If not, how could Zhuang Jianye use his old face to ask the optical company of the United States to transfer technology.

In this extremely difficult situation, Professor Chen came in muddleheaded.
