How important is laser in life?
Laser processing technology is a technology that uses the characteristics of the interaction between the laser beam and the substance to cut, weld, surface treatment, perforate, micro-process materials (including metals and non-metals), and use as a light source to identify objects. Traditional applications The largest area is green laser pointer processing technology. Laser technology is considered to be one of the indispensable tools for human survival and development in an intelligent society. For example, in unmanned driving, vehicle-mounted lidar can replace human eyes and provide the vehicle with changes in its surrounding vehicle conditions. Laser is an indispensable tool in the era of artificial intelligence. Although laser display technology was proposed as early as the 1960s, it was not until the beginning of the 21st century that the principle was first realized in my country. The principle is to use the red, green, and blue lasers as the light source, and display by adjusting the intensity ratio, total intensity, and intensity spatial and temporal distribution of the three-color lasers.

Lasers have many applications in national economic and social development. With solid-state lasers, leapfrog development in manufacturing can be achieved. For example, during the new crown pneumonia epidemic last year, a company in Xi'an relied on its years of technical accumulation in the direction of ultrafast laser precision hole making, which broke through the technical bottleneck of spinnerets in the production of meltblown cloth materials for protective masks by Chinese enterprises. After the technology was put into the market, it effectively improved the processing quality of the spinneret holes, and made a big step forward for the domestic processing of melt blown cloth. In entertainment life, lasers can also be seen everywhere, such as high powered laser projection, laser music fountain, laser color interior carving, etc. Laser has been integrated into people's daily life and has become one of the indispensable tools, making important contributions to human production and civilization progress.
