Problems solved by technology

In this case, the thermal effect has a more obvious impact on the output performance of the laser. Under the same pump power conditions, the heat dissipation structure and thermal effect processing system of the corresponding Q-switched laser are more complicated than those of the non-Q-switched laser.

Abstract

The invention discloses a laser, relating to a diode solid state laser, in particular to a method for combining multiple Q-switching pulse lasers. Multiple groups of diode solid state lasers are distributed around a center axis on a shell bracket with the same radius; laser media are distributed around the center axis of a medium disk with the same radius; a medium disk driving device drives the medium disk to rotate, so that laser media in the medium disk fall into all optical axes of the laser resonant cavity on the shell bracket; laser medium pumping light in each resonant cavity is injected in by a pump laser diode; the laser medium is activated because of realizing population inversion; a Q-switching element is opened, laser is output out of the resonant cavity; and when heat effect generated when the laser medium is irradiated by the pumping light affects laser output quality, the Q-switching element is closed, the medium disk driving device drives the medium disk to rotate, and the next laser medium in the medium disk is on each optical axis of the laser resonant cavity to restart the next operation.

Description

technical field [0001] The invention relates to a laser, in particular to a diode-pumped solid-state laser, in particular to a method for synthesizing multiple Q-switched pulse lasers. Background technique [0002] Laser diode solid-state lasers are mainly composed of pump source laser diodes, coupling systems and resonant cavities. The resonant cavity is the core part of the laser, and the laser medium is the hub to realize the conversion of pump energy into laser energy. The pump source laser diode acts on the laser medium in the resonant cavity. During the process of generating laser output, the laser medium will convert part of the energy into heat energy, resulting in thermal effect. The thermal effect of the laser medium is equivalent to adding an uncontrollable non-ideal optical element in the resonator, which often causes the instability of the laser output, affects the beam quality, and reduces the conversion efficiency of the pump light and the output laser. Espe...
