This symposium will actively respond to the "China-made 2025" national strategic planning, focusing on "laser pointer processing" and "smart manufacturing", During this time, the 2 in 1 laser pointer can spread 3.3 million kilometers, equivalent to the Earth to the moon nearly 10 times the distance. In order to improve the monochromaticity, the researchers made a close selection of the key components of the laser pen properties - the resonant cavity, as far as possible to isolate the temperature, , focusing on new technologies, new products and new trends in red laser pointer processing, combining brilliant keynote speeches for laser pen Industry intelligent transformation to provide direction and recommendations.

The line width of an ordinary laser is usually several kilohertz to several million hertz, which is not suitable for a particularly high precision test. compared to show that the line width of 10 milliseconds of these 200mw laser pointer is very stable, composed of laser All the light waves are very similar, the oscillation step height is consistent, can be synchronized in the case of 194 trillion times per second to maintain synchronization for at least 11 seconds.pressure and other external effects, and cooled to about minus 150 degrees Celsius, so that the length of the resonant cavity does not exceed hydrogen Atomic diameter of one millionth. They said that the experimental device can be further optimized, it is possible to reduce the line width to less than 1 millichromo level.At the same time in the laser area to form a "hole", the laser beam in the hole several times to reflect the material and the absorption of laser abundance quickly increased.
