abstract

A conductively cooled 970nm laser diode bar primarily designed for quasi continuous wave (qcw) pumping of miniaturized solid state lasers is presented. The robust chip design and the highly efficient two side cooling setup of the 10x12x5mm3 diode assembly allows output peak power levels as high as 600W at 500A drive current and 1% duty cycle. The high performance laser diode was employed as pump for a miniaturized, conductively cooled, side pumped Er:YAG laser system. The laser system, with an overall dimensions of 30x25x17mm3, generates 2.8W average power with M2<5.
