Abstract

The invention provides a terahertz fiber laser. The terahertz fiber laser comprises a near-infrared laser, a first collimation focusing unit, an intermediate infrared laser resonance unit, a second collimation focusing unit and a terahertz laser resonance unit which are connected in sequence. The first collimation focusing unit is used for collimating and focusing the near-infrared laser emitted by the near-infrared laser; the intermediate infrared laser resonance unit is used for generating and outputting intermediate infrared laser after the near-infrared laser collimated and focused by the first collimation focusing unit enters the intermediate infrared laser resonance unit; the second collimation focusing unit is used for collimating and focusing the mid-infrared laser output by the intermediate infrared laser resonance unit; the terahertz laser resonance unit is used for generating and outputting terahertz laser after the intermediate infrared laser collimated and focused by the second collimation focusing unit enters the terahertz laser resonance unit; and the output end of the intermediate infrared laser resonance unit, the second collimation focusing unit and the input end of the terahertz laser resonance unit are all arranged in an air chamber. The terahertz fiber laser provided by the invention has the characteristics of compact structure and simple process.

Description

technical field [0001] The present invention relates to terahertz fiber lasers. Background technique [0002] Existing terahertz fiber lasers usually use gas lasers or solid-state lasers as pump sources. However, gas lasers are bulky and difficult to integrate, while solid-state lasers require harsh working conditions, and the manufacturing process is complex and expensive. Contents of the invention [0003] The invention provides a terahertz fiber laser, which solves the problems that the pumping source used in the existing terahertz fiber laser is large in size when it is a gas laser, and its power is low when it is a solid laser. [0004] According to an aspect of an embodiment of the present invention, a terahertz fiber laser is provided, including: [0005] near-infrared lasers; [0006] The first collimating and focusing unit collimates and focuses the near-infrared laser emitted by the near-infrared laser; [0007] A mid-infrared laser resonance unit, the near-in...
