Application of conical 90-degree reflectors for solving the problem of mirror alignment in terahertz-range lasers

We report a study of the conical mirrors with an apex angle of 90[degrees] in the resonator of the gas-discharge HCN laser with the radiation wavelength of 337 mu m (0.89 THz). Experimental results have shown that such mirrors do not require precise alignment. This makes it possible to improve the r...

Zusammenfassung:We report a study of the conical mirrors with an apex angle of 90[degrees] in the resonator of the gas-discharge HCN laser with the radiation wavelength of 337 mu m (0.89 THz). Experimental results have shown that such mirrors do not require precise alignment. This makes it possible to improve the radiation stability, significantly simplify the construction of laser and reduce the complexity of its maintenance.
