Active optical system with a long-pulse CuBr brightness amplifier

摘要

Methods for changing CuBr vapor laser operating parameters by varying discharge circuit parameters of a power supply were observed. Various options of matching the power supply and the active element were tested to obtain a steady amplifying state with an atypical duration of pulse radiation. Use of the matching autotransformer made it possible to increase the power of generation two-fold and to stabilize discharge parameters at the increased input power in a medium. The pulse duration of the superradiation of 80ns was obtained in the stationary pulse-periodic operating mode. The active element can be used for monitoring the objects located at the distance more than 10m from the brightness amplifier. The comparative characteristics of the obtained images depending on the ASE pulse duration were carried out.
