A technique is suggested for enhancement of the pumping efficiency of a CuBr laser by means of modifications of the discharge circuit with a cable pulse autotransformer. The results of using four different discharge circuits are described. The experiments were carried out under similar operating conditions of the active element and at a constant input power of the pumping source. The output power increases from 14 to 21 W with the use of autotransformer and peaking capacitor. The power increase is a result of a delay between GDT current and pumping voltage and different volume-temporal characteristic of the energy input into a charge. The technique suggested can be used in different applications.
