Abstract

The invention provides a terahertz laser based on microwave excitation. A microwave source transmits microwaves into aworking substance cavity through the microwave waveguide so as to heat the workingsubstance, and after the working substance is heated, terahertz laser is formed after the working substance is cooperated with the terahertz resonant cavity formed by the terahertz high-reflection mirror and the terahertz partial reflection mirror. The frequency of the terahertz laser is the resonant frequency of the terahertz resonant cavity, so the frequency of the terahertz laser can be adjusted by adjusting the distance between the terahertz high-reflection mirror and the terahertz partial reflection mirror. In addition, the power of the terahertz laser can be adjusted by adjusting the working power of the microwave source. Compared with the prior art, the terahertz laser in the embodiment is small in size and high in energy conversion efficiency, and the formed terahertz laser is good in coherence and directivity.

Description

technical field [0001] The invention relates to the technical field of terahertz, in particular to a terahertz laser based on microwave excitation. Background technique [0002] In recent years, terahertz technology has received extensive attention and is used in various aspects such as communication, sensing, remote sensing, security, drug detection, medical treatment, and radar. [0003] All terahertz technologies and applications are inseparable from terahertz sources. At present, there are terahertz sources based on frequency up-conversion in electronic technology, free electronic devices in vacuum technology, quantum cascade devices in semiconductor technology, and optical down-conversion technology. The Hertz source is not only bulky, but also suffers from extremely low efficiency and high cost. Contents of the invention [0004] In view of the deficiencies in the prior art above, the object of the present invention is to provide a terahertz laser based on microwave...
