Abstract:

A possibility of increasing the radiation power of a CuBr laser by increasing the pumping energy is studied. For this purpose, a three-cascade system of nanosecond oscillators is used, which excite the active medium of the laser when connected in series. Each source provides a pump power of up to 2 kW. A TGI1-1000/25 thyratron is used as a switch. The pump sources perform pulse charging of the working capacitance, which ensures stable operation of the system. The use of such a power source for excitation of a gas-discharge tube 5 cm diameter and 90 cm long provides for an output power of more than 40 W in a modified scheme with pulse cable autotransformer and peaking capacitor. Tests of the source confirm its effectiveness for pumping high power metal vapor lasers.

Keywords:

CuBr laser, energy input, cable pulse autotransformer, peaking capacitor, excitation pulse duration
