Abstract
The invention belongs to the technical field of lasers, and discloses a terahertz gas laser. The laser comprises 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 first surface of the lens after passing through the first window mirror, the first surface reflects the pump light to the first end face of the terahertz hollow-core optical fiber, and the pump light enters the terahertz hollow-core optical fiber; terahertz laser in the terahertz hollow-core optical fiber is output through the second end face, part of the terahertz laser output through the second end face is output through the second window mirror after being reflected by the second surface of the lens, and the other part of the terahertz laser output through the second end face enters the terahertz hollow-core optical fiber through the first end face after being transmitted by the second surface of the lens. According to the terahertz gas laser resonant cavity with the annular cavity structure, the cavity type structure is compact and integrated, integration is facilitated, and the problems that fiber lasers with other cavity type structures are difficult to couple and complex to adjust are solved.
Description
technical field [0001] The invention belongs to the technical field of lasers, and more specifically relates to a terahertz gas laser. Background technique [0002] Traditional quartz or metal vacuum cavity terahertz gas lasers are generally large in size and high in cost. Fiber lasers have the advantages of compact structure, easy cooling, and good portability. Existing terahertz gas lasers usually adopt the structural design of linear cavity. However, the terahertz gas laser with linear cavity structure has the disadvantages of complicated optical components, difficult adjustment, and high laser loss. Contents 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 has complex structure, difficult adjustment and high loss. [0004] The present invention provides a terahertz gas laser, comprising: a gas chamber, a terahertz hollow-core fiber, a lens, a first window mirror, and ...
