Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 239: School 102 is another international shock

ASML R&D Center, Feng Linsheng is demonstrating the latest research results of 102 laser light sources.

This is not a PPT demonstration, but a physical display, or it can be said to be a technical certification.

The argon fluoride excimer laser is a laser device that uses the decay of the excited excimer ArF* to release 193nm photons. Its working principle is quite exquisite. It achieves the amplification and emission of photons through discharge and reaction processes.

When a discharge passes through the Ar/F2 mixture, Ar+ ions and electrons are produced. These electrons collide with the argon atoms and excite them to an excited state. Once an argon atom is excited, it reacts with a fluorine molecule to form the excited excimer ArF*. This excimer state spontaneously decays back to unbound argon and fluorine atoms in a transient state, emitting 193nm photons in the process.

In order to effectively amplify this excited excimer and generate laser oscillation, two mirrors are placed inside the laser to form an optical cavity. In this way, the excited excimer will cause stimulated emission and laser oscillation, further forming and decaying, releasing more 193nm photons. These photons are continuously reflected within the laser and interact with more excited excimers, producing more photons. This process is repeated, gradually increasing the number of photons.

Finally, the beam is emitted through a partially reflective output mirror, forming a powerful 193nm laser. To maintain sustained lasing, pumping maintains the required electron density and excitation. The role of the pump is to provide sufficient energy to the discharge from an external energy source to keep the laser running.

The principle seems very simple, but the pressure and temperature of the mixture, the voltage during excitation, the settings of the oscillator, the placement of the optical cavity, and of course the core is the pump. The energy output per second needs to be calculated on the computer, and Control the voltage throughout the process.

It is similar to a nuclear fission reaction. If the energy given by the pump is too little, the argon fluoride laser cannot operate stably. If the energy given by the pump is too much, the reactor may explode directly...

These require the establishment of accurate mathematical models for calculation.

The SSPPM solid-state pulse power module specially designed for argon fluoride light sources is completely a black technology of 102 Institute. The dual-cavity structure excimer laser can fully take into account both power and linewidth.

When the DC charging voltage reaches 800 volts, the operating frequency reaches 1 kilohertz, the discharge pulse rises to 90 nanoseconds, and the pulse voltage reaches 16.9 kilovolts...

Pierluigi Tammy, director of the ASML Light Source Institute, exclaimed: "Oh my God, what on earth did I see?"

A layman looks at the excitement, but when an expert sees each of these data, he has already seen a high mountain, a mountain that needs to be looked up to.

The argon fluoride technology route was not proposed by 102. As early as thirty years ago, someone discovered the phenomenon of argon fluoride excimer stimulated emission of 193-nanometer laser.

The whole world is studying how to harvest stable and high-power laser light sources.

There are more than one obstacles, and high-frequency pump power supplies and lasers are always insurmountable mountains.

The dual-cavity synchronous oscillation amplification technology is an original creation of the 102 Institute. The basic idea is to use the MO seed cavity to obtain narrow linewidth and high-quality seed light.

Generally, the output energy is small. The seed light is injected into the PA amplification cavity to amplify the light energy and obtain high-quality laser beam output with narrow linewidth and high power. The introduction of dual-cavity solid-state power supplies has greatly improved the output power of excimer laser devices.

193nm ultraviolet light is invisible to the naked eye, but the detector can detect it. Not only can it detect it, it can also measure the power of this laser beam.

"67W, the power fluctuates within 5%!"

"..." The power of 30W can enter commercial use, and 67W is already more than twice the standard.

The data from instruments such as detecting beam direction far exceeds standard requirements.

Chris Armstrong's eyes were shining. He knew very well what it would mean if ASML installed a 193-nanometer laser.

Nikon and Canon are no longer the big mountains in front of ASML. They can easily use generation differences to trample Nikon and Canon under their feet.

They want to continue to cooperate with the 102 Institute, just like the cooperation with the 246 nanometer krypton fluoride laser...

……

At this time, Paris, France...

At the 284th regular meeting of the Batumi Association, the rotating chairman country, the United States, proposed a motion.

The reasons raised by the US are still based on security considerations.

"Based on Western technology, they have developed 500-nanometer process technology. According to our investigation, they have already used this technology in the military..."

Then you can produce substantial evidence!

Of course, they also know that Europeans may not necessarily agree, so the next step is for their two dogs to perform.

Lao Maozi sees this very clearly. They think that if the United States does not say a word, then it is certain that they must have suffered a big loss...

The Koreans, on the other hand, are not soft at all. They not only talk about the military, but also the economy. DRAM memory and mobile phone communications have seized the global market, which is a serious threat to the economic security of the West...

This stick hits the sore spot of Europeans. They don't pay attention to DRAM memory. Europe has no market to begin with. But for mobile phone communications, it has to mention the GSM standard that makes Europeans cry.

"But didn't your Wall Street Journal say that WCDMA is a standard developed under the leadership of Motorola and Qualcomm? It didn't even mention the name of CITIC..."

"..."

Although there are different opinions within the industry, Western media seem to agree on the same view. WCDMA is the American standard, and Motorola and Qualcomm are the leaders in 2G communications.

Face is gained but dignity is lost, and Europe is strong in industrial control chips and application chips. This does not squeeze their living space. On the contrary, American manufacturers are aggressive.

At least French representative Jean Cloue believed: This is when the Jews started to cheat...
