Peformance data for laser diode-pumped cw Nd:YAG and Nd:BEL lasers are presented. Two single stripe laser diodes are used as the pump source, each emitting 1 W in the pump band. The heat sink for the lasers is temperature controlled to allow for wavelength tunability. The resonator is based on a hemisph Slope efficiency as high as 22% has been measured. Using different sets of output mirrors and a single birefringent plate as the intracavity wavelength-selecting element tunability over the 1167--1268 nm spectral range has been demonstrated. Continuous-wave laser operation at room temperature has been obtained for 1064-nm pumping from a cw Nd:YAG laser. The output power slope effierical design. Output and pump threshold measurements were made and gain and loss for Nd in both hosts were measured. The output power from the Nd:YAG rod was in excess of 870 mW with a slope efficiency of 58% and an overall electrical efficiency of 13%. In Nd:BEL, the output power was in excess of 635 mW with a slope efficiency of 49% and an electrical efficiency of 9.5%.
