Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in the present application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0026] Since the 488nm gas laser basically adopts the argon ion laser, the working substance is the inert gas argon, and the argon ion excitation realizes the laser generation. It is mainly used in laser display, information processing, laser spectrum research, holography, spectrum analysis, medical and industrial processing, etc. However, the argon ion laser device has complex structure, high cost, high energy consumption, low energy conversion efficiency, shor...

Abstract

The invention relates to a solid-state laser system and a control method of a solid-state laser. The solid-state laser system comprises a controller and a solid-state laser generator which are connected. The controller is used for receiving the control signal, determining a target power value and corresponding digital quantity information according to the control signal, sending the digital quantity information to the solid-state laser generator and sending a query instruction to the solid-state laser generator according to a preset time interval; the solid-state laser generator is used for receiving the digital quantity information, determining an output power value according to the digital quantity information and executing output operation according to the output power value; in response to the query instruction, an output actual power value is obtained and fed back to the controller; the controller is further used for receiving the actual power value and adjusting digital quantity information sent to the solid-state laser generator according to the target power value and the actual power value so that the actual power value can be kept consistent with the target power value. Therefore, the use safety and the output efficiency are improved, the power loss is reduced, and the output accuracy is ensured.

Description

technical field [0001] The present application relates to the technical field of industrial detection and laser application, in particular to a solid-state laser system and a control method of the solid-state laser. Background technique [0002] In industrial processing inspection equipment or other laser applications, 488nm argon ion laser systems are widely used in inspection equipment to realize the function of holography. [0003] In related technologies, the core component of the existing argon ion laser light source is a tube filled with argon gas, which is made of beryllium oxide ceramics. A high voltage is applied to the argon gas tube, and a strong voltage is generated between two hollow electrodes. Gas discharge is used to generate high-density argon ion plasma, and a magnetic field is generated around the argon gas tube to improve the output power by better confining the plasma. During production, the laser adjusts the output wavelength by installing an intracavi...
