Solid laser device

Abstract

The invention provides a solid laser, which comprises a semi-conductor laser planer array which is used to output pump light and is formed by a plurality of semi-conductor lasers, an optical coupled device which is used to couple the pump light, a resonant chamber which can output laser in parallel which is input in parallel and a laser crystal which is arranged in the resonant chamber. The invention proposes an innovative idea of simultaneously applying a plurality clusters of parallel solid laser, which effectively achieves the output of semi-conductor pump solid laser in high efficiency and big power in some extent in the parallel output mode of a plurality clusters of solid laser. The solid laser can achieve high-efficiency output through utilizing the combination of multipath lower-power laser, compared with a single semi-conductor pump solid laser, the solid laser can excellently achieve thermal dispersion since the beam-splitting output of pump light under the premise of the same output power, can reduce heat load of crystal, effectively solve the problem of thermal effect of laser crystal, and improve electro-optical conversion efficiency and the flexibility of the resonant chamber design.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a solid-state laser capable of parallel output. Background technique [0002] With the current development of semiconductor lasers, it is still impossible to use semiconductor lasers to directly obtain the output of green light; although the power level of red semiconductor lasers is relatively high, the wavelength band is relatively single; the output application of blue semiconductor lasers is currently only at low power levels (<250mw). Although the volume is small and the integration is high, the beam quality is poor and high-power output cannot be obtained. At the same time, the spectral coverage needs to be further expanded, and there is still a certain gap from practical application. [0003] The emergence of semiconductor-pumped solid-state laser technology has improved many shortcomings of previous lamp pumps. Integration and high efficiency are important research dir...
