Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described below.

[0030] A method for power self-optimization of a solid-state laser, comprising:

[0031] S1, the control system judges whether there is pre-stored power that meets the expected power according to the expected power.

[0032] S2, if it exists, the control system adjusts the current parameter combination of the solid-state laser to the pre-stored parameter combination corresponding to the pre-stored power; otherwise, the control system determines the pre-stored power closest to the expected power, and adjusts the current parameter combination of the solid-state laser to The stored parameter combination corresponding to the closest stored power.

[0033] Preferably, the method for determining the combination of pre-stored parameters includes:

[0034] Determine the pre-stored power, the pre-stored power is not greater than the maximum output power of the solid-state laser;

Abstract

The invention discloses a power self-optimization method of a solid-state laser, and relates to the technical field of solid-state lasers, the method uses a control system to adjust the output power of the solid-state laser to meet the expected power, if not, parameter combination is coarsely adjusted to enable the output power to meet the expected power, then the parameter combination is finely adjusted, and the output power of the solid-state laser is thus stabilized. By means of the control system, monitoring of parameters of all modules of the solid-state laser can be achieved, high-precision control and adjustment of parameters such as current, temperature and position can be achieved, it is guaranteed that all the modules work in the most effective state, automatic optimization and adjustment of laser power are achieved, and it is guaranteed that light emitting power is stable; furthermore, the control system can monitor the working state of the laser and automatically detect the performance of the laser.

Description

technical field [0001] The invention relates to the technical field of solid-state lasers, in particular to a power self-optimization method for solid-state lasers. Background technique [0002] Ultraviolet solid-state lasers have great application value in the fields of optical measurement, atomic and molecular physics, spectroscopy, nonlinear optics, laser medical treatment, lidar and photoelectric countermeasures, and have become a frontier topic in the field of electro-optical device research. From microlithography From marking and printing, the application of ultraviolet lasers is the fastest growing part of the industrial laser market, which should be attributed to the very mature all-solid-state ultraviolet laser technology and the unique advantages of short-wavelength lasers in processing. [0003] The power of the ultraviolet solid-state laser needs to be stable during use. Once the power fluctuates, it will bring difficulties to subsequent applications. Performanc...
