Study of scalability of capacitive excited CuBr lasers

Abstract

In this work, we study experimentally the output performance of a middle-scale CuBr laser with longitudinal capacitive discharge excitation. Lasing power dependencies on different operating parameters are studied, including the equivalent electrode capacitance value. An average output power of 12 W, the maximum to date, has been attained in the CuBr laser excited by a longitudinal capacitive discharge with ∼0.5% efficiency. This result has been obtained with a total calculated electrode capacitance of 1190 pF on the each side of the gas discharge active region.
