Abstract

The invention belongs to the technical field of lasers, and discloses a terahertz gas laser, which includes a gas chamber, a terahertz hollow-core optical fiber, a lens, a first window mirror, and a second window mirror pump; the pump light enters the lens after passing through the first window mirror The first surface of the terahertz hollow-core fiber reflects the pump light to the first end face of the terahertz hollow-core fiber and enters the terahertz hollow-core fiber; the terahertz laser in the terahertz hollow-core fiber is output through the second end face and passed through Part of the terahertz laser output from the second end face is reflected by the second surface of the lens and then output through the second window mirror, and another part of the terahertz laser output through the second end face is transmitted through the second surface of the lens and enters the terahertz laser beam through the first end face. hollow core fiber. The invention adopts the resonant cavity of the terahertz gas laser with the annular cavity structure, and the cavity structure is compact and integrated, which is convenient for integration, and avoids the problems of difficult coupling and complicated adjustment of fiber lasers using other cavity structures.

Description

technical field [0001] The invention belongs to the technical field of lasers, and more particularly, relates to a terahertz gas laser. Background technique [0002] Traditional quartz or metal vacuum cavity terahertz gas lasers are generally larger in size and higher in cost. Fiber lasers have the advantages of compact structure, easy cooling, and good portability. Existing terahertz gas lasers are usually designed with a linear cavity structure. However, the terahertz gas laser with a linear cavity structure has the disadvantages of complicated optical components, difficult adjustment, and high laser loss. SUMMARY OF THE INVENTION [0003] By providing a terahertz gas laser, the present invention solves the problems in the prior art that the terahertz gas laser is complex in structure, difficult to adjust, and high in loss. [0004] The invention provides a terahertz gas laser, comprising: a gas chamber, a terahertz hollow-core optical fiber, a lens, a first window mir...
