Abstract

In this paper a CuBr pulsed laser ((lambda) equals 510.6 nm and 578.2 nm) having an average output power of 10 W and efficiency (2,5%) is presented. Owing to a considerably lower operating temperature (560 degrees Celsius) CuBr laser becomes an alternative for more widely used conventional Cu laser (with operating temperature 1500 - 1600 degrees Celsius) in such applications where the required laser output power is lower than 50 W. Examples for such applications, mainly for high precision laser machining in electronic are presented in this paper.
