all solid-state blue laser light source is expected to be widely used in many fields, such as digital to analog converter, laser and brush technology, laser medicine, biochemical technology, material science and optical communication.

As metal processing technology continues to advance and user requirements continue to increase, lasers need to innovate in terms of cost and energy efficiency as well as laser system performance.For non-ferrous metals, the absorption of light energy increases with the decrease of light wave length.For example, the light absorption of copper at the wavelength below 500nm will increase by more than 50% than infrared light, so blue semiconductor laser is more suitable for the processing of copper.

A blue-violet semiconductor laser refers to a semiconductor laser with an oscillation wavelength of about 410 nm. In addition to being used as a light source for Blu-ray discs and the like, it is also expected to be used as an illumination light source, a display light source, and the like. Blu-ray discs use varieties with an oscillation wavelength of 405 nm. The blue-violet semiconductor laser is the basic component of the new generation of optical discs after DVD.

Using a blue semiconductor light source with a wavelength of 450 nm, the copper material can be melted in the thermal conduction mode, so that the molten pool geometry of the thin copper material can be precisely adjusted.

Laser technology is considered to be one of the essential tools for human survival and development in the intelligent society.Such as sweeping robot, vehicle-mounted laser radar and so on.At present, major countries in science and technology attach great importance to the research and application of laser technology, China also attaches great importance to the research and application of laser technology, such as high efficiency and precision laser additive manufacturing - ecM overall manufacturing technology, femtosecond laser precision manufacturing application basic research projects in the national Key RESEARCH and development program.
