Vertical discharge type static state carbon dioxide laser device

Abstract

The invention relates to a vertical discharge type static state carbon dioxide laser device. The vertical discharge type static state carbon dioxide laser device comprises a discharge tube, wherein two ends of the discharge tube respectively have a first end cover and a second end cover, an inner side face of the first end cover or of the second end cover is provided with a tail mirror and an output window, and the inner side face of the first end cover or the second end cover is further provided with at least one folding reflector. According to the vertical discharge type static state carbon dioxide laser device, great laser output power can be acquired in a space of the discharge tube, so miniaturization of the vertical discharge type static state carbon dioxide laser device can be realized, and applicability is improved.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a longitudinal discharge type static carbon dioxide laser. Background technique [0002] At present, for the traditional glass discharge tube longitudinal discharge type static carbon dioxide laser, since the laser medium gas is in a closed static state, to obtain a large laser output power, it is necessary to increase the length of the discharge tube (that is, increase the optical resonance cavity length) to achieve. However, when the length of the discharge tube increases, the laser will also become longer accordingly, thus losing its use value. [0003] In order to solve the above problems, lasers with V-shaped folded optical resonators, parallel folded optical resonators and cross-folded optical resonators appeared to shorten the length of the laser and obtain greater laser output power. Among them, the patent number is ZL00116695.6, and the patent named "V-shaped plane crossed three-...

AI Technical Summary

Problems solved by technology

[0004] However, this folded optical resonator also has problems

For example: when using the V-shaped folding technology, since the material of the discharge tube is usually glass, the angle between two adjacent discharge tubes cannot be too small; when using the parallel folding technology, the adjacent two discharge tubes A certain distance must be kept between the tubes so that the transverse optical path between the two discharge tubes can be connected through two reflectors at an angle of 45 degrees to the optical paths of the two discharge tubes, which will also cause the vertical discharge type static carbon dioxide laser volume increase

In addition, the structure of the above two existing technologies is folded with the discharge tube as the unit, and each discharge tube needs to be equipped with a pair of electrodes to inject electric power for discharge excitation

It can be seen that there are still shortcomings such as insufficient compactness in the overall structure, which affects the popularization of this kind of laser in application.
