Calculation and experimental study of the energy and amplifying characteristics of the active medium of a cw chemical HF laser

The theoretical approach of W W Rigrod is used to describe the dependence of the output radiation power of a cw chemical HF laser with an inhomogeneous distribution of the small-signal gain in the active medium on the reflection coefficient of the output mirror of the cavity. The adopted approach is used to develop a calculation and experimental method for determination of the properties of active media of lasers of this type. This method is then applied to determine the energy and amplifying characteristics of a compact HF laser and to predict the parameters of a large-scale laser.
