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

    Theoretically, this is true. Let alone the 170 nanometer range, as long as the method is appropriate, even a water droplet can compress the laser wavelength to below 100 nanometers.

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

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

    However, solid crystal laser components have a natural flaw, that is, they cannot enter the deep ultraviolet region below 200 nanometers, so high-energy lasers cannot be obtained.

    The kbbf crystal just solves this problem. It uses unique coupling optical materials of nonlinear crystal structure components to successfully obtain a 176-nanometer deep ultraviolet high-energy laser body.

    Based on this, high-energy lasers equipped with kbbf crystals can carry out targeted high-energy damage to damaged satellites between 40 kilometers and 80 kilometers away from the ground according to the guidance of the aerospace measurement and control station, thereby avoiding the generation of space junk or terminating damage.  The spacecraft crashes to avoid losses to people and property on the ground.

    As for the Air Force's hope of installing this set of equipment on the IL-76 large transport aircraft to create an aerial laser platform; and the Navy's hope of transplanting this equipment onto warships to create a sea-based interception device, that is all a matter for later. Anyway, related projects have already begun preparations.  , Ascendas Group has already started preliminary research in this area.

    In addition to military uses, kbbf crystals are also widely used in industry. For example, the next generation of 3D printing equipment being developed by Ascendas Group uses kbbf crystals as its core laser components; another example is the new generation of Ascendas Group¡¯s 3D printing equipment.  The laser precision welding robot also uses kbbf crystal.

    There is also the first-generation domestic deep ultraviolet lithography machine jointly developed by Ascendas Group and whnb Semiconductor. The core component of the laser etching equipment is the kbbf crystal.

    For this reason, Luan Heping, one of the founders, chairman and co-CEO of whnb Semiconductor, has almost not considered Ascendas Group as his home during this period. He almost eats, drinks and eats at Ascendas Group just to stare at the domestic deep ultraviolet lithography machines.  schedule.

    The reason for this is very simple. Once the domestic deep ultraviolet lithography machines using KBBF crystals are put into mass production and put into use, whnb Semiconductor will be able to directly sell chips made of 193 nanometers at a cabbage price, thus expanding the market share and converting mid- to low-end products.  End chip manufacturing is fully embraced.

    It can be said that Ascendas Group¡¯s domestic deep ultraviolet lithography machine is a key link in Luan Heping¡¯s whnb semiconductor assembly from low-end to mid-range, and there is no room for sloppiness.

    It is the trump card of the headquarters, the tactical weapon system of the navy and air force, the key manufacturing equipment of aerospace, and the key to the semiconductor industry.

    Since the day kbbf crystal was born, it has become the key to the upgrading of domestic industries in various fields.

    The problem is that kbbf crystals are not potatoes from farmers¡¯ fields. They are dug into sacks. After all, they are high-tech optical materials, which are not easy to prepare.

    As of now, it is not possible to mass produce on a large scale and can only be prepared on a small scale in the laboratory.

    However, Professor Chen, now the deputy director of the Gangxue Research Institute of Ascendas Group, has begun research in this area, and it is expected that a reasonable large-scale industrial preparation plan will be provided in the next two to three years.

    Speaking of Professor Chen, he is a strange person. He was once the master's tutor of Hu Rongyi, a senior researcher at the Institute of Optics of Ascendas Group.

    After taking care of students like Hu Rongyi, Professor Chen was transferred to Fujian Province and served as a researcher at the Institute of Physics of the province. In the early 1990s, the Institute of Physics of Fujian Province responded to the call for reform and began to establish its own physical business units and adopt market-oriented methods.  Manage scientific and technological achievements based on the principle of humanization.

    At that time, the institute hoped to operate six listed companies within five to eight years. On the one hand, it would improve the salary of scientific researchers within the institute, and on the other hand, it would also solve the problem of insufficient research funds.

    Among them is the laser solid device research group led by Professor Chen.

    The problem is that the listing review was very difficult at that time. Provinces basically gave indicators to state-owned enterprises with good industrial prospects but current difficulties, in the hope that these enterprises could tide over the difficulties through listing and financing.

    As a result, the listing process of Professor Chen's research group became far away, so he, like the leaders of other research groups, put pressure on the institute, and at the same time, the Eight Immortals crossed the sea to show their magical powers and make connections everywhere.

    Professor Chen didn¡¯t know where he heard that his student Hu Rongyi was doing well in Ascendas Group and was able to speak to the top management of Ascendas Group.

      You must know that although Ascendas Group in the early 1990s also had some problems in its own development, it was much better than most companies. More importantly, Ascendas Group had extremely strong profitability and was the major shareholder of China Merchants Bank.  And China Merchants Bank controls many companies in the Special Administrative Region and Hong Kong Island. If we also count whnb Semiconductor, the king of coastal semiconductor foundries, and Qiongdao Airlines, the representative of civil aviation reform, together with all these miscellaneous things, Ascendas Group is simply one of the capital giants.  big mac.

    ¡°It¡¯s definitely the kind that can make the Shanghai and Shenzhen stock markets tremble when you sneeze.

    In addition, during that period of time, Ascendas Group and the management were going back and forth, and finally ended with a major change of management, and Ascendas Group joined hands with several aviation manufacturers to successfully land a leather bag company on the Hong Kong stock market.

    It even makes the outside world think that Zhuang Jianye, the head of Ascendas Group, has a big backer. No matter what the indicators or plans are, as long as Zhuang Jianye says a word, everything will be given the green light.

    It was precisely because of such rumors that Professor Chen wanted to try his luck with his students.

    "A few years ago, Professor Chen, who was full of old-school intellectual ideas, would never let go of this face. The problem was that he didn't think about himself, but he also had to think about his group of technical staff.

    You must know that many people have been following him in the research of nonlinear crystal optical components since the 1970s. For more than 20 years, they have endured countless hardships and suffered many hardships in the coming and going, but they have always suffered.  I persevered, and now I can finally see the flowers and fruits, and use knowledge to change my life. I can't be stuck here just because of the difficulty in approval.

    So Professor Chen thought about it for two days and two nights, studied countless rhetoric, and finally made up his mind and hurriedly boarded the train north to Hebei Province to find his students.

    At that time, Ascendas Group encountered unprecedented difficulties in the field of high-energy lasers. At that time, Ascendas Group did not think about solid laser components, but at that time, gas lasers were still the mainstream route for high-energy lasers around the world, even in the United States.  The KDP crystal they lead is only used as a tactical-grade laser weapon component. High-energy lasers such as deep ultraviolet and extreme ultraviolet can also be realized with gas or liquid lasers.

    The problem is that no matter whether it is liquid or gas, let alone Ascendas Group, there is nothing good that can be obtained in the entire country. If not, how could Zhuang Jianye have the nerve to ask an American optical company to transfer technology.

    In this extremely difficult situation, Professor Chen broke in without knowing what was happening.
