Terahertz gas-discharge laser with exit cone mirror

In the terahertz range of frequencies (from 0.1 to 10 THz) gas lasers are among the most common and available generators. However, the structural complexity and the complexity of service is a significant drawback of these lasers. Highly qualified personnel, is required even for the maintenance of gas-discharge lasers, which are relatively simple. Adjustment of the resonator mirrors - this is one of the most critical and complex operations that have to perform at service of such lasers. Development of laser resonators that do not require adjustment of the mirrors is an important task.
