Description

technical field [0001] The invention relates to a controller, in particular to a controller used for an all-solid-state high-power laser. Background technique [0002] There are various types and forms of high-power lasers (power above 1KW) currently in use, but generally they are still based on CO 2 laser for multiple, CO 2 Lasers were born earlier and matured for metal welding and metal surface cladding, but because their beams are transmitted through rigid pipes, they are only suitable for two-dimensional or external simple three-dimensional welding. All-solid-state diode-pumped solid-state high-power lasers that can be transmitted through optical fibers to solve and make up for such problems and shortcomings are the mainstream development direction of high-end high-power lasers at home and abroad. However, the current high-power all-solid-state lasers in China are mostly in the stage of working in the laboratory. Their operation control is relatively simple and rough, ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the cumbersome control operation, low efficiency, inability to link with external equipment, and lack of necessary protection for the current all-solid-state high-power laser, which causes the laser to be easily damaged and has a reduced lifespan, which is not conducive to the long-term reliable operation of the laser, etc. To solve the problem, it is necessary to provide an all-solid-state high-power laser universal controller with compact structure, strong control function, easy operation and error-free operation, comprehensive safety protection function for the laser in the working process, and communication linkage with external equipment.
