Copper vapor laser with a wavefront-reversing mirror induced in the active medium

A study was made of the operation of a copper vapor laser and a resonator with a dynamic wavefront-reversing mirror induced in the active medium by a four-wave interaction with pump waves excited in an auxiliary resonator. Radiation with a diffraction-limit divergence was generated in a resonator with a convex second mirror. The energy, time, and spectral characteristics of lasing were determined.
