Technology principle

 

The ultra-fast laser has extremely short operating time and high peak power, which can directly ionize the materials in the affected area and realize "Cold processing" with high-precision, low damage and other processing advantages which cannot be achieved by the long pulse laser. And thus the ultra-fast laser has been widely used for micro-machining applications.

The long pulse laser utilizes the thermal accumulation of laser energy to melt the material in the active region to volatilization, and a large amount of debris and microcracks are generated in the process, and the longer the duration of the laser, the larger the heat affected zone.

The ultra-fast laser can inject huge energy into the material in a very short time, directly interrupting the molecular bond of the material to make the material in the active region instantaneously ionize, and the material is removed at the microscopic scale.
