Method of two-pulse frequency regulation of copper-vapor laser parameters

A method for a wide-range control of the laser action parameters of a metal-vapor laser on self-limited transitions without violation of the heating regime is described. The method is based on the formation of an additional control pulse with each of the excitation pulses without laser action, and the regulation is realized by variation of the delay between the pulses. The method was tested with a copper-vapor laser. It is shown that the control of the lasing parameters is realized by changing the prepulse population of the metastable level of the active medium.
