Back to the Republic of China to be a editor

"Ms. Zhao, it's done!" A window on the fourth floor opened, and a student poked his head out and replied loudly.

"Crack", a searchlight on the roof was turned on, and with a not too high power gear, it shone on the truck parked in the open space.

All saw the illuminated truck.

"Lasers are not only gorgeous and colorful, they are also a kind of...weapon. Now please students on the fourth floor, use lasers to blow up this truck!"

Teacher Zhao waved his hand, and after a while, all the lights in the surrounding buildings went out, which means that the electric switch was pulled.Now, all the electrical energy in Tsinghua University has become the dedicated circuit for high-power lasers on the fourth floor.

In the classroom on the fourth floor, all kinds of strange machines, cables, and pipelines filled a classroom with 60 people.

Tang Hua, Prime Minister, and Nie Shuai returned to the steps above the teaching building, and handed each of them a pair of sunglasses to wear.

The test begins.

Tang Hua first saw a twinkling red dot in the engine compartment of the truck, which was the hit point where the students upstairs were calibrating the laser.

Calibrating the hit points only takes a few seconds.Then the little red spot disappeared, and a bright spot of high brightness suddenly appeared on the truck, and the bright spot quickly began to turn red again, and then with a "boom", the whole truck exploded into a ball of fire.

silence.

Quiet.

The prime minister said nothing.

Ambassador Luo Shen opened his mouth wide, and the pipe slipped from his hand unknowingly.

Nie Shuai took off his glasses vigorously, and stared at the ball of fire in front of the building with his naked eyes.

Zhou Xuan, who was sheltering from the cold in the room of the teaching building, was also dumbfounded and did not speak.

In the classroom on the fourth floor, just 10 seconds of irradiation work triggered the full work of the water cooling system, the laser was humming, and smoke and mist were still rising from the outside.

The nearly [-] students, teachers, and teaching staff present were the first to come to their senses.

"Oh!!"

"Successful!" "Laser Cannon! Successful!"

"Physics Department! Physics Department!"

Amidst the cheers of the audience, Tang Hua pointed at Zhao Zhongyao and Qian Sanqiang, and said loudly: "Mr. Zhao Zhongyao and Qian Sanqiang are the inventors of the laser!"

More than half of the cheering audience were students from the physics department. They immediately dragged Zhao and Qian down, and then the students formed a pile and threw Zhao Zhongyao and Qian Sanqiang into the sky.

"Teacher Zhao! Teacher Zhao!"

"... Department of Physics! First Department of Tsinghua University!"

……Um?Was this way of celebrating invented so early?

"Oh, science students look down on liberal arts students, foreign language students look down on Chinese literature students, Chinese literature students look down on philosophy students, philosophy students look down on sociology students, sociology students look down on education students, education students don't have anyone You can look down on them, but you can only look down on the teachers in your department. This is true of any university, and Tsinghua University is no exception. Today is the physics department at the top of the discrimination pyramid, showing off, I’m leaving!”

"Shut up, Fang Hongjian." Tang Hua looked back, "Oh, no, Mr. Qian Zhongshu... you should say a few words and go back quickly..."

Before Tang Hua had time to say hello to Mr. Qian, he was also dragged into the crowd and thrown upwards.

"I'm not an inventor, I just came up with an idea..." Tang Hua said while flying in the sky.

The laser was given to Teacher Zhao by Tang Hua.is compensation.

Mr. Zhao voluntarily left the forefront of physics research in Europe and America, and spent the rest of his life only teaching and educating people in China for decades.Because of this choice, he is likely to miss the Nobel Prize.The country cannot afford to spend money to do cutting-edge theoretical physics research.

Although the laser is an invention of applied physics, it is also a heavyweight enough to win the Nobel Prize.Especially if the application of lasers blossoms everywhere in the next few years and penetrates into all aspects of human life, then the Nobel Prize will be more stable.

"Academician Tang Hua, I hope you don't just show off all this to me tonight." Ambassador Luo Shen came over and said to Tang Hua.

"As I said before, China and the Soviet Union are friendly allies. I think our two countries can work together for it. The laser is the sharpest weapon, but it is not yet. If the scientists and engineers of China and the Soviet Union Together, we may be able to weaponize it in the shortest possible time."

"Can you share the prototype of this weapon with us?"

"Of course, this requires a higher level of communication and permission between our two countries. But personally, I have no objection to this. In fact, on the theory of lasers, the paper we wrote last month has been sent to Moscow, and soon will get a response."

After listening to Tang Hua's words, Luo Shen had a genuine smile on his face.

Let you just stare at the road of laser hard killing and get stuck for decades.

What Tang Hua thought was actually this.

Chapter 1, The Laser Family

The news of the public demonstration of the laser was not publicly reported in the newspapers. Now the focus of attention of all walks of life and mass cadres is also on the front line of the War to Resist US Aggression and Aid Korea. The laser was born in such a low-key manner.Of course, it is considered low-key from a national perspective, but in Tsinghua University and the Electronic Information Industry Bureau, the sensational effect is still not small.

When Zhao Zhongyao, Qian Sanqiang, and Tang Hua walked into the small auditorium of the Department of Physics, the prolonged applause from the audience proved how shocking the "laser show" was the night before yesterday.

"classmates,"

Tang Hua was not at the podium, so he pulled a table over and sat down first.

"In fact, Mr. Zhao proved 20 years ago that the Chinese are capable of standing at the pinnacle of world science. The Chinese are no worse than any other nation or race. The birth of the laser the day before yesterday proved that the Chinese not only Top-notch scientific research can be done abroad, and top-notch scientific research results can also be made domestically, so as to make our contribution to the scientific progress of all mankind."

applause……

"Laser is a research result of fundamental physics. Of course, it is not a theory, but a kind of entity to verify the basic physical theory. The so-called technology includes basic science, applied science, engineering technology, and the final results It is a product. Now that we have solved the theoretical basis of basic science through basic research, the next thing to do is to quickly transform the breakthrough of basic science into applied science, and then transform the applied science into engineering technology solutions, and produce some that can give A product that brings revolutionary changes to our lives. Teacher Zhao and Professor Qian have already divided you into groups before, so now we will—confide in the tasks and then split up!"

In the small auditorium, there were more than 20 students from the Department of Physics who were graduating this year—there are not many students in the Department of Physics of Tsinghua University, so they almost caught them all at once.

"One more thing, all of you here are eligible to study for a master's degree without examination. The topic of your master's thesis is the task I will distribute later. Develop something, write it into a graduation thesis, defend it, and complete it. The first Group, Zhu Guozhen, Liang Guiming."

Tang Hua looked at the two students who were sitting together now.

"What you are going to develop is a laser irradiator. I saw the laser you used to illuminate the ground the day before yesterday. It is quite good. It can be made a little smaller. Probably... the weight is about the same as a light machine gun. The function is also good. Just like the show the night before, send out a beam of low-power laser light, and the photoelectric light shines on something two kilometers away. It would be better if it could be farther away. That's it. Oh, the laser shines on, the spot should be relatively stable , can’t float around, so it’s good to have a bipod or tripod.”

Bipod tripod, isn't that really a machine gun?Zhu Guozhen and Li Qingzhong looked puzzled.

"I can't tell you too much in detail, just do it. By the way, you can finish this in a few months, remember to remind me, I will assign you new tasks after finishing this." Tang Hua thought, Your secret level is still the one you waited for at the beginning, and you haven't been able to understand the whole plan yet.

"The second group..." Tang Hua looked at the name of the group leader of this group and thumped.

"Zhou Guangzhao, your five-member team."

"Your group is not only exempted from the exam to study for a master's degree, but also a master's-doctoral degree. Why? Because the things entrusted to you cannot be completed in three years, as long as you can do it before your doctoral degree. You... are the laser communication group. Laser It is also light and electromagnetic waves, which are the same as medium-wave and short-wavelength waves. So I want to make a set of equipment composed of laser generators and receivers to receive and send information like a radio station. At the master’s level, you can first carry out theoretical research research and validate calculations."

Zhou Guangzhao stared wide-eyed, looking at the "problem opening report" (actually information and technical requirements) handed over to him just now.

The mentor of this group is Zhao Zhongyao.Using laser to transmit information can be done in the laboratory, and the technology can be shared with the optical storage group behind.But the real communication needs to wait for the optical instrument factory to be built, and to upgrade the optical fiber based on the optical glass manufacturing equipment; the other is the semiconductor laser and the fiber laser.Only when these two external conditions are in place can this group of people graduate... But think about Zhou Guangzhao holding a shiny CD in his hand, and a book as tall as a building that P went up under his feet. The narration of the photo is "In my hand There is as much information stored on your laser disc as there are books under your feet", which is interesting.

"The third group, Sun Liangfang's group of 4, you are the optical storage group. In fact, you have many similarities with the research direction of the second group. Sometimes you might as well study and research together. You... are also master-doctoral students. Optical storage is of course not using laser as a carrier of information storage and letting it float in the air at a speed of 30 km/s, but using laser when reading and writing information. This is also for you for six or seven years time."
