Optimization of the CuBr+Ne+HBr laser excitation source

In this work, an experimental and model analysis of the copper bromide vapor active media excitation efficiency was carried out at a fixed energy input and pump power. The experimental results showed that for typical pumping parameters of CuBr+Ne+HBr active elements, the requirements for the excitation source in terms of the voltage amplitude on the storage capacitor can be reduced. It was shown that the reduce of voltage amplitude from 11.3 to 6.6 kV while maintaining the energy input at the level of 1 mJ/cm3, leaded to the generation power decreased by 15%, and the single-pass amplification coefficient remained virtually unchanged. Simulations have shown that at lower capacitance values, the lower operating level of the laser is populated a little more strongly, but pumping of the upper operating level during the existence of population inversion also proceeds somewhat faster, which ultimately gives approximately the same efficiency of pumping.
