Embodiment 1

[0035] according to figure 1 An all-solid-state blue light laser is produced in the optical path. After the laser crystal Nd:YAG is end-pumped by the semiconductor laser, the fluorescence of 946nm, 1064nm and 1319nm is produced. When the fluorescence of these three wavelengths passes through the prism group (3), (9) After being separated, it reaches the cavity mirror (1) after passing through the PPKTP or BBO crystal. Adjust the cavity mirror (1) to make the fluorescence of 946nm return to the original path to generate resonance, while the fluorescence of 1064nm and 1319nm cannot return to the original path to form resonance. In this way, it is ingenious The 1064nm and 1319nm spectral lines with large emission cross-sections are effectively suppressed from oscillating. The cavity mirror (1) is a flat mirror, one side is coated with a 946nm, 473nm high-reflection film, the cavity mirror (6) is a flat-concave mirror, and the concave surface is coated with a 946nm full-reflectio...

Embodiment 2

[0037] Example 2: Press figure 2 A high-power all-solid-state red, yellow, and blue laser device is constructed to output quasi-continuous blue light. The cavity mirror (1) is a plano-convex mirror. ) selects a plano-concave mirror, and the concave surface of the plano-concave mirror is coated with a 946nm total reflection film; a nonlinear optical crystal (2) selects a periodically poled potassium titanyl phosphate crystal with a polarization period of 6.2 μm, and places it in the resonant cavity Between the mirror (1) and the Brinell angle prism (3), the laser with a wavelength of 946nm is frequency-multiplied into 473nm blue light; two pieces of the Brinell angle prisms (3) and (9) with an apex angle of 69.1° are placed according to the Brinell angle ; A piece of Nd: YAG laser crystal (5) is placed between the Brinell angle prism (9) and the acousto-optic Q switch (8); the Q switch (8) is placed in front of the resonator mirror (6) for producing quasi Continuous laser; th...

Embodiment 3

[0039] Embodiment 3: press image 3 A high-power all-solid-state red, yellow, and blue laser device is constructed to output continuous wave blue light. The optical path is the same as that of Embodiment 1, except that the pumping method is different. This embodiment adopts the side pumping method.

[0040] Adjust the resonator mirrors (1) and (6) to make the 946nm fluorescence oscillate, then output the continuous blue light of 473nm at the Brinell corner prism (3).

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...
