Design of multipass telescopic amplifiers for a cw chemical HF laser

The results are given of calculations (carried out within the geometric optics approximation) of the energy parameters of multipass telescopic amplifiers for a cw diffusion HF laser. A brief description is given of the calculation method. Two known types of telescopic amplifier are compared with a conventional single-pass configuration. The dependences of the output parameters on the input signal, resonator gain, and coupling coefficient are investigated.
