Description

Lamp pump laser

[technical field]

The utility model relates to a kind of laser, relates in particular to a kind of lamp pump laser.

[technical background]

The fixed form kind of the laser reflection cavity of traditional lamp pump laser is many, and relatively more commonly used is directly by the hard briquetting of two flat boards being pressed in the two ends of laser reflection cavity.Because laser reflection cavity generally adopts hard ceramic body or metallic object to make, therefore, when the hard briquetting with two flat boards directly is pressed in the two ends of laser reflection cavity, the first, cause laser reflection cavity to be damaged by pressure easily; The second, be adjacent to and contact because briquetting and laser reflection cavity are direct two planes, thereby make that cooling water is difficult for circulating.

In addition, be used to filter the ultraviolet use glass tube that always is in the laser, this glass tube manufactures cumbersome, and cost is also than higher, and dimensional accuracy is not well guaranteed yet, if adopt sheet glass, just can well address the above problem.

Therefore, how to provide a kind of both effective fixed laser reflection cavities, the laser of the lamp pumping that can reduce production costs again just becomes the problem that current urgent need will solve.

[summary of the invention]

The purpose of this utility model is to provide a kind of both effectively fixed laser reflection cavity, the lamp pump laser that can reduce production costs again.

For achieving the above object, a kind of lamp pump laser of the utility model comprises base and is installed in housing, end cap and krypton lamp protective device on the base, enclosure interior is assembled with laser, be assembled with light-filtering glass in the laser, the two ends of described housing are connected with end cap respectively, and the outside of described end cap is connected with the krypton lamp protective device; Between housing and the end cap briquetting is installed, briquetting also is installed in the two ends of laser, wherein, described briquetting comprises a substrate, and substrate is provided with boss, offer a groove on this boss, put a packing ring in the described groove, the center of described substrate offers a through hole, and this through hole protrudes out to the center, hole in its inwall and forms two stoppers, this stopper is divided into two cavitys with described through hole, offers bar-shaped trough on the described stopper.

The utility model lamp pump laser is by setting up boss and adding packing ring on this boss on the briquetting, thereby make not only effective fixed laser of this briquetting, avoid laser to be damaged by pressure, and because the end face of laser is to contact with boss on the briquetting, therefore, between the end face of laser and briquetting, just form certain space, can help the circulation of cooling water, strengthened cooling effect.In addition,, can effectively light-filtering glass be held, thereby can adopt with light-filtering glass replacement filter glass pipe in the past, to reach the effect that reduces production costs by on the stopper that is provided with on the briquetting, offering bar-shaped trough.
