Problems solved by technology

[0002] At present, in the existing laser device technology, it mainly emphasizes that the 808nm optical pump source enters the Nd-YV04 crystal at one time, so as to excite the maximum laser energy as much as possible, and one pump source has only one laser resonance path; thus, for The length of the cavity of the laser resonator has a small adaptation range, which increases the technical difficulty of the production of the laser resonator cavity

Embodiment Construction

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Shown with reference to Fig. 1, 2, it discloses a kind of laser device, and it mainly comprises: rear mirror 1, crystal 2, crystal 3, front mirror 4, optical pumping source 5, optical fiber connector 6, collimating lens 7 and Focusing head 8, where:

[0019] The rear mirror 1 is a plano-concave mirror, and the incident point of the optical pump source 5 deviates from the center of the end face of the crystal 2 (which can be a YV04 crystal) to control the position of the laser output.

[0020] The radian R of the rear mirror 1 is 100mm-2000mm, coated with a film, one side is fully transparent for 800-970nm light, and the concave surface is fully reflective for 1050-1380nm light.

[0021] The crystal 2: a-cut, 0.2%-2% Nd Doped, coating...

Abstract

This invention discloses a laser device comprising: rear plano-concave lens; the incidence of light pumping source is deviated from the center of YVO4 crystal end surface by 0-2mm; under the rear lens is equipped with a rear lens regulator; under the Q-SW crystal is equipped a Q-SW crystal regulator; above the front lens is equipped a lens regulator; in front of the rear lens is equipped with a focusing unit; in front of which unit is equipped with a parallel light regulating lens; before said lens is the optical fiber splice; under said lens is the lens regulator. During the use of said device, the pumping source produces two laser resonance paths, so it can increase laser conversion, the Nd-YVO4 is heated evenly, with advantages of greater adaptive-range: 40-200mm, so lowering the difficulty of the production of the laser resonator cavity.

Description

technical field [0001] The invention relates to a laser device, in particular to a laser device capable of causing an optical pump source to generate two-way laser resonance. Background technique [0002] At present, in the existing laser device technology, it mainly emphasizes that the 808nm optical pump source enters the Nd-YV04 crystal at one time, so as to excite the maximum laser energy as much as possible, and one pump source has only one laser resonance path; thus, for The adaptable range of the cavity length of the laser resonator is small, which increases the technical difficulty of the production of the laser resonator cavity. Contents of the invention [0003] The invention provides a laser device, which can overcome the existing defects. One optical pumping source can generate two laser resonant paths, so that the length of the laser resonant cavity can be adapted to a large range, and the production of the laser resonant cavity is reduced. technical difficult...
