Long-Pulse Copper Bromide Laser

In this paper the results of investigation of copper bromide vapor laser with pulse duration up to 320ns are presented. For pulse extension, the system of limitation of discharge current, based on a composite switch consisting of a thyratron and a tacitron connected in series, was used. This method allows to limit the excitation of lasing transitions in the initial stage of the discharge, thereby increasing the inversion lifetime. Researchers have shown that the longest duration of lasing is achieved with relatively low pulse repetition frequencies (2-5 kHz) in tubes of a medium and large diameter.
