Surface mount device (SMD) type solid laser, and adjusting device, and manufacturing method for SMD type solid laser

Abstract

The invention discloses a surface mount device (SMD) type solid laser. The SMD type solid laser comprises a laser diode (LD) pump light source and a resonant cavity, wherein the resonant cavity comprises a laser crystal, a frequency doubling crystal and a plane output mirror which are parallel with one another; and the LD pump light source, the laser crystal, the frequency doubling crystal and the plane output mirror are fixed in the corresponding grooves of a laser substrate sequentially. In addition, the invention also discloses an adjusting device and a manufacturing method for the SMD type solid laser. The SMD type solid laser has a plano-plano cavity structure; the laser substrate serves as a mina supporting body; and the corresponding grooves are formed in the laser substrate, so only the positions of the optical components are adjusted, the optical components can be fixed in the corresponding grooves, and the manufacturing steps are simplified.

AI Technical Summary

Problems solved by technology

[0003] Today, solid-state lasers have not yet been mass-produced. The reason is that when assembling solid-state lasers, a single optical element is inserted into the optical path and manually adjusted and positioned one by one. Traditional solid-state lasers use a flat-cavity structure. Because the resonant cavity of this structure is a point resonance, only one point in the concave surface resonates with the plane mirror, so the adjustment is time-consuming and laborious.
