Embodiment Construction

[0033] The terms "first", "second", "third" and so on are only used for distinguishing descriptions, and do not represent sequence numbers, nor can they be understood as indicating or implying relative importance.

[0034] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are absolutely horizontal or overhanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal than "vertical", and it does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0035] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", "left", "right", "upper", "lower" etc. are based on the Orientation or positional relationship, or the orientation or positional relationship that the application product is usually placed in use, is only for the convenience of des...

Abstract

The invention discloses a laser device and a method for stabilizing emitted laser, and relates to the technical field of laser equipment. The laser device comprises a supporting seat, a light-emittingpart, a cylindrical lens and a basic heat sink, wherein the supporting seat is provided with a mounting space; the light-emitting part is arranged in the mounting space and comprises a laser chip anda chip heat sink; the cylindrical lens is connected to the supporting seat and is positioned at the opening of the mounting space; the fast axis direction of the laser chip faces the cylindrical lens, the cylindrical lens is used for collimating the fast axis of the laser chip, and the supporting base and the chip heat sink are both welded to the basic heat sink. According to the invention, fastaxis collimation is carried out on the light emitted by the light-emitting part through the cylindrical lens, so the divergence angle of the laser chip in the fast axis direction can be compressed, and the pumping efficiency and the uniformity of the pumping light are improved. Besides, the supporting seat and the chip heat sink are welded to the same basic heat sink, so light spots formed by thelight-emitting part after fast axis collimation are more stable, and the stability of the laser device is higher.

Description

technical field [0001] The present application relates to the technical field of laser equipment, in particular, to a laser device and a method for stabilizing the emitted laser light. Background technique [0002] A laser device is a device that can emit laser light. The commonly used laser device is a semiconductor laser device that pumps a solid-state laser crystal. [0003] In the prior art, a laser device generally includes a support base and a light-emitting element installed in the support base. The light emitted by the light-emitting element is generally emitted directly, so that the fast axis divergence angle is relatively large, and the pumping efficiency and the uniformity of the pump light are relatively high. Low. [0004] Due to the change of the divergence angle of the fast axis, the emitted laser light is not stable, so the light spot formed by the light emitting element is unstable. Contents of the invention [0005] The purpose of the present applicatio...
