The original chinese name of laser is "Laser", which is a transliteration of its english name LASER, which is an abbreviation composed of the first letter of each word taken from the English Light Amplification by Stimulated Emission of Radiation. Means "light expansion by stimulated emission". The full English name of laser has fully expressed the main process of manufacturing laser, and the principle of laser has been discovered by the famous American physicist Albert Einstein as early as 1916. In 1964, according to the suggestion of Qian Xuesen, a famous Chinese scientist, "photostimulated radiation" was renamed "laser".
Thick and thin plates of automobile body, automobile parts, lithium batteries, pacemakers, sealed relays and other sealed devices, as well as various devices that do not allow welding pollution and deformation. Currently used lasers are YAG lasers, CO2 lasers and semiconductor pumped lasers.

Laser drilling is mainly used in aerospace, automobile manufacturing, electronic instrumentation, chemical industry and other industries. The rapid development of laser drilling is mainly reflected in the fact that the average output power of the YAG laser for drilling has increased from 400w five years ago to 800w to 1000w. At present, the relatively mature application of laser drilling in China is in the production of synthetic diamond and natural diamond wire drawing dies, as well as in the production of gem bearings for watches and instruments, aircraft blades, and multi-layer printed circuit boards. The lasers currently used are mostly YAG lasers and CO2 lasers. There are also some excimer lasers, isotope lasers and semiconductor pumped lasers.

Lasers are widely used in the electronics industry. It can be used for precision machining of micro instruments, fine scribing of fragile and fragile semiconductor materials, and adjustment of the resistance value of micro resistors. With the improvement of laser performance and the emergence of new lasers, the application of laser in VLSI has become a key skill that many other processes cannot replace, showing an encouraging prospect for the development of VLSI. The advent of the laser sparked a revolution in the printing industry.
