Compact laser module and laser

Abstract

The invention discloses a compact laser module. The compact laser module comprises a heat-radiating and conductive packaging shell, openings are formed at two ends of the packaging shell, a sealing cover and an output mirror are arranged at the openings at the two ends respectively, an LD pumping laser light source, a focusing collimation spherical mirror, a laser crystal and a nonlinear frequencydoubling crystal are sequentially arranged in the packaging shell between the sealing cover and the output mirror, the positive pole of the LD pumping laser light source penetrates the sealing coverto be led out, and the negative pole of the LD pumping laser light source is connected with the packaging shell. The present invention further discloses a compact laser. The laser module is configuredto package the LD pumping laser light source, the focusing collimation spherical mirror, the laser crystal and the nonlinear frequency doubling crystal for whole heat dissipation through the packaging shell, the size is small, the heat dissipation is uniform, and the structure is simple; and moreover, the laser is configured to arrange a plurality of laser modules side by side on the base, and heat dissipation is performed by employing a built-in heat conductive tube to form a high-power laser.

Description

technical field [0001] The invention relates to a compact laser module and a laser, belonging to the technical field of lasers. Background technique [0002] In recent years, the projection display market based on laser technology has developed rapidly and has attracted widespread attention. At the same time, the demand for higher power red, green and blue primary color lasers has also increased significantly. Among them, the technology of red light and blue light laser is relatively mature and has been widely used. Although green lasers have made some progress, they still have a certain distance from mass production. Therefore, high-power and low-cost compact green lasers are the technical bottleneck in the laser display industry today. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a compact laser module and laser. [0004] In order to achieve the above object, the technical scheme adopted in the presen...
