Abstract

The invention relates to the technical field of laser, and particularly relates to an optical pumped gas laser comprising a vacuum waveguide tube (1), optical bridges (5), an input coupling reflecting mirror (19) and an output coupling mirror (25). The two ends of the vacuum waveguide tube (1) are installed on the optical bridges (5) via a fixed end base (2) respectively. The fixed end base (2) and an output mirror base (3), and the fixed end base (2) and an input mirror base (4) are respectively connected in a sealing way via welded bellows (17). The periphery of the external side of the welded bellows (17) is provided with a fine adjustment device and spring locking devices. Longitudinal mode selection of the gas laser is realized, precise fine adjustment is realized, output light beam quality of the laser is guaranteed, the structure is enabled to be compact and stability is enhanced so that the optical pumped gas laser has excellent precision, linearity, stability and repositioning, and the whole equipment has high rigidity.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to an optically pumped gas laser capable of precisely adjusting the cavity length at the nanometer level while maintaining a high vacuum state. Background technique [0002] Optically pumped gas lasers (the most typical such as gas terahertz lasers) generally have low working pressure, and the absorption spectrum of gas atoms or molecules to pump light is narrow. Under this condition, in order to realize the extraction and conversion of the pump light to the stimulated radiation amplification light of the required wavelength, the following technical problems need to be solved: the spatial mode coupling between the pump light and the oscillating laser, the absorption of the pump light by the laser medium, the laser Longitudinal mode selection of the resonator, thermal management of the laser medium, and optical stabilization of the system, etc. Theory and experience show that the vac...
