Lin Hanwen continued: "However, because this black bone company is different from other companies, I heard from Tan Ju that they have real materials, and the breakthroughs and achievements in strong AI are also world-remarkable.

Therefore, if they really solve the commercialization problem of the corresponding laser pulse equipment in the femtosecond category, I think it is also very possible.

After all, Japan, Europe and other places also have these technologies, but attosecond-level lasers have always been the world's most cutting-edge science and technology, and China is still tracking the pace of international research, and international research is also stuck at this level.

Even if the Black Bone Company has great ability, it is unlikely that it will lead the world in this ultra-high-end optical field.

Of course, it's still the same sentence, I still won't draw conclusions until I really see the results, what if this company surprises us again?"

At the end of the words, Lin Hanwen smiled, and the last sentence, even he felt that the probability was slim, not one hundredth, but one in billion.

Because, Lin Hanwen has also studied the history of black bones and their situation in the optical laboratory in the past few days.

The person in charge of the optical laboratory of Black Bones is Li Kaishan, this guy Lin Hanwen knows, not only has he communicated before.

In Lin Hanwen's view, this is a scientist who is more than conservative and lacks innovation, and the black bone optical laboratory may last for a long time under his leadership, but the probability of making any major breakthroughs is almost zero.

Even, in Lin Hanwen's view, the re-launch of the fullerene device by Black Bone Electronics is not because they have really made a breakthrough in technology, it is very likely that they reached an agreement with the company in Japan and bought the technology in their hands at a high price.

After listening to Lin Hanwen's analysis, Luo Xianjun fell into silence.

To be honest, he doesn't quite agree with Lin Hanwen's relatively fixed cognition.

Because, through understanding, Luo Xianjun really discovered the second-generation fullerene plasma polymerization device of Black Bones, which has improved by leaps and bounds compared with the first-generation device in terms of efficiency, power consumption, volume and functional diversity.

From these aspects, it should be true that Black Bones' laser technology has made a breakthrough, which is more advanced than that of that company in Japan.

Moreover, Luo Xianjun later went to ask Tan Jianhua specifically, and learned from Tan Jianhua's mouth that Black Bone's commercial laser pulse equipment entered the 100 attosecond field, and this news was said by the boss of Black Bone, not misinformation, and the authenticity is very high.

However, before seeing the real results, everything has not yet surfaced, and those who engage in scientific research like to look at the facts.

Lin Hanwen was like this, and so were Luo Xianjun and the others in the bus.

After the group arrived at the optical laboratory of Black Bones, they were received by Jiang Bo, Ke Peng, Li Kaishan and others.

After exchanging a few words briefly, Tan Jianhua pulled Jiang Bo aside and asked: "Mr. Jiang, this group of experts is specially recruited by me from Yanjing, and they are all well-known scholars in the field of optics.

"It seems that Tan Ju has no confidence in me. Jiang Bo said.

"It's not that I'm not confident, but this matter is too big, as the boss of the black bones, Mr. Jiang, you know a lot about laser pulses, right?"

"It's ok. ”

"Then you should know what a pulse of 100 attoseconds means, right?" Tan Jianhua said in a deep voice: "The attosecond pulse laser, since its appearance, has been hailed as one of the most important milestones in the history of laser science, and the application prospect is immeasurable.

At present, it has become an important research method in many fields such as physics, chemistry, biology, etc., and has also been successfully used by some Western laboratories to measure and control the movement of bound electrons in the inner shell, expanding the world's vision of studying the structure of matter from molecules to atoms.

Not only that, it has also led to many major scientific and technological advances in the fields of X-ray, free electron laser, controllable high-temperature superconductivity, ultra-high-resolution imaging, and electronic information processing. ”

"I know that. Jiang Bo nodded slightly.

Jiang Bo doesn't know much about laser pulses, but it's not too little.

It is no exaggeration to say that attosecond laser pulse technology is equivalent to opening the door to the study of the extremely ultrafast motion process of electrons.

However, because attosecond science has just emerged, the current research is still in its infancy, and Huaxia is still keeping up with the international pace, although the research results in some aspects are good, but on the whole, it is still far from the world's first echelon.

If Black Bone announces that the 100 attosecond laser pulse can enter the commercial stage, then there is no doubt that Huaxia's research in attosecond science will cross the first echelon, achieve corner overtaking, and directly lead the world by half a step.

Therefore, Tan Jianhua attaches great importance to this exchange visit.

Jiang Bo said: "Tan Ju, no matter how much I talk to you now, I can't help it if you don't believe me, let's talk about things with reality." ”

"Actually, I still believe most of your words......" Tan Jianhua smiled.

Jiang Bo didn't answer, and after greeting Li Kaishan, he entered the optical laboratory with everyone.

The two atomic-level processing equipment is the highest secret of the optical laboratory, and naturally cannot be leaked, so for the content of the exchange group's visit, Black Bones also has reservations.

Because the experts had a lot of problems, Li Kaishan couldn't cope with them, so he took them directly to the research and development center and used the test results to speak.

The testing process is not as complicated as imagined, but can be done directly with a scanning autocorrelator.

By using an electric motor to drive a quartz block to rotate, then the beam of the two arms can be provided with a delay according to the path of the beam propagating in the quartz block, and then through the strong AI analysis from the black bone, the laser pulse duration, that is, the pulse width, can be effectively identified.

The test ended quickly, and the row of numbers displayed on the big screen was all 99.6AS!

"A pulse duration of 99.6 attoseconds...... How, exactly?"

"It's unbelievable. ”

"But this test is too haphazard, isn't it? It's just a test of the scanning autocorrelator, and that's the end of it......"

"I haven't seen the behavior of the laser pulse, so it's not convincing. ”

Hearing the discussion, Li Kaishan knew that they didn't believe it, and he didn't get angry, so he immediately ordered several researchers to carry out a more tedious and clear test.

The testing methods, including the second harmonic correlation method, the two-photon fluorescence method, the high-speed fringe camera method, and the higher order correlation method, all require equipment in the optical laboratory.

After grinding for half an hour, this group of experts from Yanjing all put their doubts behind them, and turned to horror and shock on their lips.

"This is incredible, there are really people in our country who can achieve the pulse in the 100 attosecond field, and it is also a stable output, and the power per unit time has reached the MW level!"

"Professor Li has repeatedly proved that there is nothing to doubt, the laser pulse of the black bone is indeed at the level of 100 asecond, which is a big breakthrough. ”

"I swore it was impossible, but now, alas, my face is a little red. ”

"Is it just a little red? It still hurts. ”

"Ahem, you guy, you don't speak and no one thinks you're dumb!"
