CONICAL 90° MIRRORS FOR TERAHERTZ LASER RESONATOR
要約
In the mid part of the terahertz range (1 THz) gas-discharge lasers are among the most common and available oscillators. Alignment of the resonator mirrors is one of the most critical and complex operations that have to be performed while using such lasers. Development of laser resonators that do not require adjustment of the mirrors is an important task. A study of the conical mirrors with an apex angle of 90° was considered. These mirrors are tested in a laser cavity. The tests were carried out in a gas-discharge HCN-laser at a wavelength of 337 microns (f ~ 0.89 THz). Experimental results have shown that such mirrors do not require precise alignment. This makes it possible to improve the stability of the radiation, to simplify the design of the laser and to reduce the complexity of its maintenance.
