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 relates to a high energy diode pumping solid laser realizing method, which is characterized in that a plurality of groups of diode pumping solid lasers are distributed on a casing bracket in the same radius around a central axis; laser medium is distributed in the same radius around a central axis of a medium plate; a medium plate drive device drives the medium plate to rotate, so as to ensure that the laser medium on the medium plate enter into the axes of all light rays output by laser resonant cavities on the casing bracket; pumping laser diodes on end surface and side surface emit pumping light to the laser medium in all the resonant cavities, the laser medium in the resonant cavities realizes population inversion and is activated, and the resonant cavities generate laser output; and when a thermal effect is generated while the laser medium is irradiated by the pumping light to affect laser output quality, the medium plate drive device drives the medium plate to rotate, again the laser diodes on the end surface and the side surface emit pumping light to the laser medium in all the resonant cavities, and the lasers generate laser output.

Description

technical field [0001] The invention relates to a laser, in particular to a diode-pumped solid-state laser, in particular to a high-energy diode-pumped solid-state laser method. 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. Especially ...
