Influence of acoustic perturbations of the active medium on the stimulated emission from a pulse CS2/O2 laser

The two-pulse photoinitiation method was used in an experimental study of optical inhomogeneities in the active medium of a pulse chemical CS₂/O₂ laser. It was found that these inhomogeneities were due to transverse acoustic waves resulting from the pulse ultraviolet illumination of the active gas mixture. The resonator losses due to these waves were about 10^–2 cm^–1.
