Abstract:

Results of experimental studies of two different-size high-frequency active elements of a CuBr laser operating in generator, single-pass amplification, and superradiance modes are presented. A pulse repetition rate of 195 kHz is attained for the first time in the supperradiance mode. Using the method of express estimation of the radial profile, it is shown that the gain profile does not change significantly throughout a wide pulse repetition rate range (up to 195 kHz) in the case of a small-diameter active element.

Keywords:

copper bromide active medium, laser monitor, pulse repetition rate, radial profile, supperradiance
