Abstract

The invention discloses a terahertz gas laser for electron beam pumping. The terahertz gas laser comprises an electron gun, a first vacuum pumping system, a terahertz detector, an off-axis parabolic mirror, a coupling hole, a collector, a second vacuum pumping system, a gas storage tank, a pressure sensor, a gas chamber, a vacuum cavity and a resonant cavity. The invention provides a new mode for generating terahertz radiation by using an electronics technology, namely an electron beam pumped terahertz gas laser, which is not only an extension of a terahertz wave band of a gas pumped laser, but also a new innovation direction of an electron beam terahertz radiation technology.

Description

technical field [0001] The invention belongs to the technical field of terahertz radiation sources, in particular to an electron beam pumped terahertz gas laser. Background technique [0002] Traditional electron beam laser research is divided into several categories. First: In the last century, a large number of electron injection pumped gas lasers were developed, using high-energy electron beams to inert gases such as Xe, Kr and Ar. second, electron beam pumped KrF laser research; third, low-energy electron beam pumped XeI to produce far-infrared laser research work, using 5-20KeV electron beam, injected into the gas chamber through a small hole, And interact with the gas to produce 1.73 micron infrared light radiation. However, most of the electron beam lasers designed by the traditional electron beam laser research institutes pump the range of visible light (up to ultraviolet and infrared), and do not use the terahertz wave below the infrared band in the spectrum as the...
