The Prosperous History of China's Chemical Laser

China’s laser technology has reached the international trend list, but many people don’t know the difficulties involved. Let’s review the development history of chemical lasers in China.

The one who has been engaged in chemical laser research in China is the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. It has been engaged in chemical laser research for more than 50 years. 'Innovation, to the successful development of China’s first HF/DF chemical laser, and then to the successful development of China’s first oxygen-iodine chemical laser, special HF/HBr chemical laser key technology breakthroughs, chemical laser research has realized from scratch, from childhood From the big, from the weak to the strong, from theoretical basic research to key technology research, and then to technology integration, continuous breakthroughs, continuous upgrades, and continuous surpassing.

Since its establishment, the Institute of Chemical Research has been facing the needs of major national missions. As early as July 1960, American scientist Mayman made the world’s first ruby u200bu200blaser. In 1961, Canadian scientist Polanyi first proposed the idea of u200bu200brealizing infrared chemical lasers through chemical reaction to generate vibration rotation layout reversal. Western countries have begun to explore the use of lasers as various optical weapons. The leaders at that time gave special instructions, and we also engaged a group of people. Go study it.

In 1962, the Institute of Chemical Technology established a chemical laser research group. Under the situation that the basic knowledge of chemical laser was weak and the western countries blocked us from technology and equipment, it began a difficult exploration. In 1966, it successfully developed The first HCl chemical laser pumped by light-induced chemical energy was released, which was only two years later than the world’s first pulsed HCl chemical laser made by American scientists Kasper and Pimentel.

In order to make lasers have greater energy, better quality, and higher efficiency, my country has officially begun research on high-energy chemical lasers. In 1973, the Chemical Laser Laboratory was established. In 1974, it successfully developed a combustion-driven continuous wave high-power HF/DF chemical laser. While developing laser-related equipment, it also studied the mechanism and basic theories of chemical lasers, and started a new “pumping”. 'Research on the dynamics of energy transfer between reactions and molecular collisions has opened up the field of molecular reaction dynamics in my country.

In 1982, my country successfully developed the first oxygen-iodine chemical laser, which opened the prelude to my country’s high-energy short-wavelength oxygen-iodine chemical laser research. In 1994, the oxygen-iodine chemical laser made a new breakthrough. The volume of the laser has been improved by an order of magnitude, and the oxygen-iodine chemical laser technology has entered the world's advanced ranks, and the success of the technology is highly valued by the country.

The scientific researchers at that time, regardless of the crude conditions, worked hard, and promoted the continuous development of chemical laser research. Today’s chemical laser research laboratory is no longer the original dozen people, but has become a team of hundreds of people. The organizational structure has changed from horizontal to vertical. The experimental base has also changed from tens of square meters to the current two. More than 10,000 square meters, with hundreds of international advanced instruments, let us see the tremendous development of the chemical laser laboratory. I hope that the new generation of researchers will continue to develop chemical lasers.
