Abstract

This invention relates to a laser especially high power solid red, yellow, blue laser device including a pump laser, two cavity mirrors, a laser crystal, nonlinear optical crystal, and one or more than two tuned prisms, in which the pump laser is mounted in front of a cavity mirror, the laser crystal tuned prism and nonlinear optical crystal are orderly mounted on the optical path between two cavity mirrors in which the tuned prism is fixed on an angle tunable horizontal rotating stand. Other optical elements are mounted on a angle tunable optical platform applying a prism and two cavity mirrors to constitute a single path or double paths frequency multiplication light path overcoming the shortcoming of difficult to coat film or to suppress 1064 nm fluorescent polarization.

Description

technical field

[0001] The invention relates to a laser device, in particular to a high-power all-solid-state red, yellow and blue laser device. Background technique

[0002] Usually the laser emits lasers of multiple wavelengths at the same time, for example: Chinese patent application number: 981028314, the name of the invention is: "a laser that simultaneously outputs red, green, and blue ternary colors", it is in two resonant cavity mirrors or 1-3 pieces of optical superlattice crystals are placed in sequence, and the pump light is placed in front of a resonant cavity mirror; wherein the optical superlattice crystals are used as a parameter medium and a coupling parameter medium. The nonlinear effect of the optical superlattice material is used to obtain the sum frequency, difference frequency or parametric output, and it uses the cavity mirror coating to select the spectral lines incident on the optical superlattice material. However, the...
