Chapter 1047 Breaking the Technology Monopoly

Previous page        Return to Catalog        Next page

    No wonder Aziz was so surprised that his brain broke into pieces, because he knew very well how difficult it would be for the nb-6600dl to compress the laser to 355 nanometers.

    Although nb-6600dl uses the same laser generation, reflection and refraction structure as a lithography machine, nb-6600dl is fundamentally different from a lithography machine.

    Think about it and you will know that the laser application material of the photolithography machine is high-purity silicon; while the nb-6600dl application belt material is an alloy containing various metals such as nickel, rhenium, and niobium.

    In other words, the laser energy density of nb-6600dl is much greater than that of the photolithography machine. Otherwise, it would be impossible to drill process holes in such high-strength metal.

    If you want the energy of the laser to be high, then according to Planck's formula, the wavelength of the laser must be as long as possible. However, this brings about an unavoidable difficulty, which is the problem of compression of long-wavelength lasers.

    Just like water in a water pipe, how to spray water farther and more accurately is to either increase the water pressure at the output end or reduce the nozzle to increase the pressure of the water flow.

    The same is true for laser processing. If the high-energy laser is not compressed, the holes will not be holes but holes.

    Currently, there are many lasers that compress laser wavelengths around the world. The problem is that most lasers do not have long durability for high-energy-density lasers. For example, the commonly used carbon dioxide lasers. Once the energy density of the laser increases, it will either  Let the carbon dioxide consumption inside the laser increase exponentially; or it simply cannot hold it and explodes directly.

    Therefore, this type of carbon dioxide laser is rarely used on this type of high-energy laser equipment. There is no way, the workpiece has not been completed, and it may be necessary to replace three or four carbon dioxide lasers.

    This is no different from replacing four engines of a car before it has been driven three hundred kilometers. The cost is simply too high.

    But now, the nb-6600dl that Zhuang Jianye showed them can not only compress high-energy lasers to 355 nanometers, but more importantly, it has been almost twenty minutes since Aziz and others came in, and a flame has almost been processed inside the nb-6600dl.  The tube was broken, but the most easily damaged laser not only did not have any problems, it still continued to work vigorously, even more vigorously than when Aziz was young and slept with twenty beautiful girls.

    What does this mean?

    Renjia Tengfei Group has found a new high-energy laser compression method that is stable, sustainable and has been applied in industrial production.

    It was not only Aziz who realized this, but other knowledgeable aviation experts from both countries thought of this issue. Then when they looked at nb-6600dl, their eyes were different, as if they were seeing alien creatures, their eyes were full of  The surprise of reality and the doubts of the unknown.

    "Mr. Zhuang, how does your nb-6600dl do it?"

    Knowing that he had lost his composure with his surprised exclamation, Aziz quickly took two deep breaths to steady his old heart that was beating wildly. Then he calmed his tone and asked again: "I mean, how can you do this?"  Compress the high-energy laser that penetrates the alloy material to 355 nanometers?¡±

    "Oh, we use a nonlinear crystal solid material called 'lithium triborate crystal' as the main material of the laser. Of course, the name is too long, so we generally call it lbo crystal, which can do 3 times  Frequency doubled ultraviolet laser." Zhuang Jianye replied with a smile.

    "Nonlinear crystal solid-state laser? Have you applied it to this extent in China?"

    Aziz was really shocked now. You must know that only the United States and Europe can independently produce solid-state lasers in the world, and the United States has the most advanced technology.

    As early as the 1960s, kdp crystals, also known as potassium dihydrogen phosphate crystals, were developed. With the advancement of technology, Americans have accumulated a lot of technical experience and patent barriers in kdp crystals.  It is the leader in the field of optics, and in the mid-1980s, it dared to propose Star Wars and developed so-called laser weapons to attack Soviet nuclear missiles.

    Because the ultraviolet laser generated by the frequency doubling of the KDP crystal by high-energy laser has strong energy, it is enough to destroy any spacecraft flying in outer space, including nuclear warheads.

    Because of this, the Americans have very strict control over this type of high-end optical materials. The top-quality ones are not exported at all. Only the next-generation products that have been eliminated by the military will be distributed among U.S. allies in a controlled manner under the operation of certain technology companies.  diffusion.

    Europe picked up these scraps used by Americans and built kdp crystal solid state lasers. Not only is the performance one to two generations behind that of the United States, but more importantly, the technical path used by Europe is exactly the same as that of the United States.  Therefore, huge patent fees need to be paid to the United States every year.

    The situation in Europe is pretty good. Although patent fees are paid, the United States is in a special transatlantic relationship. In addition to restricting Europe's use of kdp crystal-related technologies in outer space, there are no other fields.How many restrictions.

    Japan, South Korea and other countries do not have such good treatment. Not only are patent fees paid, but the application fields of kdp crystals are also strictly restricted by the United States, especially those areas that are in direct conflict with related US companies. Japan, South Korea  As for other countries, let alone entering, even if you put a hair into it, the Americans can set off a prairie fire and burn you to ashes.

    Let¡¯s not talk too far, let¡¯s just say that a few years ago, Japan wanted to launch a satellite to monitor the dynamics of the ocean around Japan. It needed to be equipped with a laser detection equipment and needed a kdp crystal. At that time, the Japanese optical giant Canon felt that this project was purely for civilian use.  In addition, I have been authorized by the United States, so I should be able to produce it independently. There is no need to take off my pants and fart before telling my American dad, just produce it on my own.

    As a result, the American father was furious when he got the news. He didn't expect that Japan's good grandson had hard wings. If he didn't tell himself about the core kdp crystals used in the production of civilian satellites today, he would have to hide it from himself when he builds a space-based laser weapon tomorrow.  ?

    So without saying a word, they directly seized all the kdp crystals produced by Canon on the grounds that it violated the agreement. Then the Tokyo District Prosecutor's Office special investigation team stationed in Canon and the Japan Aerospace Planning Agency, and soon became involved in a major corruption case.

    It ended with the head of Canon¡¯s optical affairs department hanging himself, the director of the Japan Space Planning Agency in charge of optical detection equipment being arrested and imprisoned, and Japan¡¯s $400 million monitoring satellite was forced to be cancelled.

    ¡° Americans suppress even one civilian equipment like this, let alone others, but countries around the world can¡¯t do anything about the United States. Who lets others hold the core technology?

    And core technology means technological hegemony.

    But now Ascendas Group's nb-6600dl is openly producing combustion chambers for aircraft engines. That is an aircraft engine. Whether it is for military or civilian use, it is a taboo that Americans value. The Chinese actually use solid materials that Americans are strictly guarded against.  laser for processing.

    What does this mean?

    Ascendas Group has completely broken the American technology monopoly!
