Abstract
A cavity for flat gas laser is composed of laser tube supporter, the front and back regulating frames of the reflecting mirror in resonant cavity, light beam gathering unit and trimming mechanism of flat laser tube. Said trimming mechanism of flat laser tube consists of upper and lower seats of laser tube and at least one of them is adjustable. Said upper and lower seats of laser tube are arranged on the laser tube supporters above and under the installation position of flat laser tube for regulating it easily.
Description
The present invention relates to a kind of cavity for flat gas laser, especially a kind of being used for by many cavitys near the laser of arranging that flat Gas LASER Tube constituted.
Gas laser requires and can make adjustment to laser tube with cavity, and existing cavity for flat gas laser need could be realized adjustment to laser tube by adjusting many screws, so, this adjustment difficulty is big, in addition, because the restriction of the self structure of this cavity makes it can't be used for the gas laser of being made up of many flat laser tubes that are arranged in parallel, thereby has limited the raising of flat gas laser complete machine power.
Goal of the invention of the present invention is to provide a kind of cavity for flat gas laser that flat Gas LASER Tube is adjusted of being convenient to.
The present invention adopts following technical scheme to realize its goal of the invention:
The present invention is a kind of cavity for flat gas laser that is used for laser, form by adjusting bracket 3, beam convergence device 4 and flat laser tube micro-adjusting mechanism 5 behind adjusting bracket 2, the cavity mirror before laser tube support 1, the cavity mirror, flat laser tube micro-adjusting mechanism 5 is made up of laser tube upper bracket 51 and laser tube undersetting 52, and wherein having a bearing at least is adjustable seats, and laser tube upper bracket 51 and laser tube undersetting 52 are located at respectively on the laser tube support 1 of the above and below that is positioned at flat laser tube installation site.
Compared with prior art, the present invention has following advantage:
1. since the present invention above the laser tube and above be provided with upper and lower bearing, therefore, can not be subjected to prop up therewith the influence of another mutually close laser tube of laser tube during adjustment, have sufficient adjustment space, be convenient to the adjustment of laser tube.
2. the setting of upper and lower slide block only needs the bidimensional that can realize flat laser tube by moving up and down of slide block and twists and adjust, and therefore, the employing of the technical measures of upper and lower slide block has further facilitated the adjustment of laser tube.
3. the concrete technical scheme of adjusting bracket before the cavity mirror that is adopted among the present invention, it adjusts the top that the space is positioned at laser tube, and this zone in the time laser tube adjust the influence that is not subjected to other laser tubes, therefore, the adjustment of whole laser tube that this concrete technical scheme is further easy again.
4. the present invention be suitable for laser, particularly the present invention that flat Gas LASER Tube forms above technical measures are comprehensive use after, it is adapted at more by using on many lasers that constitute near the flat Gas LASER Tubes of arranging.
