Abstract

The invention relates to a compact carbon dioxide pumping terahertz dual-frequency laser, which comprises a dual-laser main body, a carbon dioxide laser pumping light path and a laser auxiliary system, the dual-laser main body comprises a pumping end vacuum cavity, an output end vacuum cavity, two laser tubes, four invar bars and a pumping end vacuum cavity; the whole carbon dioxide pump light path and the dual-laser main body are fixed on an optical panel, and laser emitted by the carbon dioxide laser enters a cavity through different brewster windows after being subjected to condensation and beam splitting; the output end vacuum cavity is shared by the two terahertz lasers, a high-precision three-dimensional adjusting mechanism is used for fixing the center hole copper mirrors and remotely adjusting the length of resonant cavities of the two lasers under the sealing condition, namely the distance between the two center hole copper mirrors at the pumping end and the output end, and the length of the resonant cavities is accurately adjusted, so that the output power and the difference frequency of the terahertz dual-frequency laser can be controlled.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a compact carbon dioxide pumped terahertz dual-frequency laser. Background technique [0002] Terahertz wave refers to electromagnetic radiation with a frequency in the range of 0.1-10THz (wavelength 3000-30 microns), which is located in a fairly wide range of electromagnetic radiation between microwaves and infrared light. It includes a section of the electromagnetic spectrum from part of the millimeter wave band (about 0.1THz) to the far-infrared region (about 25THz). A light source capable of generating laser light in the terahertz frequency band is called a terahertz laser, and a terahertz laser is an important light source for far-infrared laser interferometers in plasma diagnostic technology. [0003] Plasma electron density is an extremely important physical parameter in the experimental research of tokamak fusion devices. It is related to many physical phenomena and can...
