It contains providing the continuous material of green laser pointer .
Nearly a hundred times the body compression. A major breakthrough in this series of laser fusion research advanced in the world, but also laid the foundation for future long-term sustainable development. Of laser science and technology, although it suffered a decade-long calamity of the "Cultural Revolution", but by means of the support of key projects are still struggling to survive and has made valuable progress. After the reform and opening up, China's laser technology has gained unprecedented development opportunities. May 1980, respectively, in Shanghai, Beijing held the first International Laser Conference. Delegates 218 66 (foreign), Comrade Deng Xiaoping cordially met with the foreign representatives attending the meeting. 1983 in Guangzhou and in 1986 held in Xiamen, a second, the Third International Conference. The supply management of green laser pointer is the best.
In July 1985, the laser device on the 12th time and put into trial operation. The successful test run three laser shooting test, the valuable results achieved the expected goals. The device is the largest high-power neodymium glass laser device in the international arena is also one of the few large-scale laser works. It consists of the laser system, system range, measuring diagnostic system and the experimental environment engineering systems. The output laser power of up to one trillion watts of magnitude, while the laser time only billionths of a second one to ten billion one. Available lens to the size of 50 nm, can produce 10 trillion billion watts / cm 2 power density. This beam is focused on the surface of the material. More green laser pointer can be supplied.
Experiment to correct the minimal deviation of the instrument due to vibration and temperature changes, so that the output laser accurate by focusing through a small hole of about 0.3 mm, only a little thicker than a hair. Determine the performance of ultrashort laser system there are two important indicators: First, the time scale, the second is the output power. In April 2004, SG Ⅱ device 100 trillion watts mark output peak power of 120 trillion / 36 femtoseconds. At present, only a few developed countries in the international well-known experimental titanium sapphire laser device output power of over 100 trillion watts. This means that God means that God trillionth of 36 seconds ultrashort moment within the light II in 1000 trillionth of a second ultra-short moment.
