ABSTRACT:
A high effieciency pumping scheme mode matches the TEMOO laser mode volume with a plurality of spaced apart laser diode pumping sources positioned along a lateral side of a block of laser material. The cavity resonator within the block is configured in tightly folded zig-zag configuration. Pump radiation from the diode pumping sources is collimated by an optical fiber and the fold angle is selected to mode match the pump radiation to the mode volume. Parasitic oscillation across the laser block are prevented.
