✦ Synopsis

This paper reports on the characterization of a diode-side-pumped CW Nd:YAG laser. A side-pumped conÿguration with 9 laser diodes is used for the laser. Pump light is directly coupled into the Nd:YAG rod without focusing lenses and the pump light distribution in the Nd:YAG rod was calculated. A maximum output power of 150 W in multimode operation is obtained for a pumping power of 400 W. The optical-optical e ciency is 37%. Output power of the laser under di erent output couplers, resonator lengths and temperatures of the cooling water have been studied.
