Abstract
The paper presents the results of experimental study of middle scale CuBr laser performance with longitudinal capacitive discharge excitation. Lasing power dependences on various operating conditions were investigated including the influence of equivalent electrode capacitance value. Maximum average output power of 12 W with ~0,5% efficiency was reached in CuBr laser excited by longitudinal capacitive discharge. These results were obtained with total calculated electrode capacitance of 1190 pF on the each side of a gas discharge active region. Linear growing of lasing power with increasing of input power is observed at all values of electrode capacitances and indicates the perspective of further increasing of output power of capacitively excited CuBr lasers.
