摘要：

A 10 W laser-diode bar, a multistripe monolithic laser-diode array, has been used to end-pump Nd: YAG. Twenty beams emitted from 20 stripes, spaced 500-mu-m apart, of a 1 cm linear diode array were collimated by a 1 cm wide lens array consisting of 20 GRIN (graded-index) lenses with a width of 500-mu-m to pump the Nd: YAG facet. The maximum Nd: YAG CW output power at 1064 nm of 3.24 W CW was obtained at 8.6 W incident pump power with a total electrical-to-optical conversion efficiency of 10.1%, a threshold of 0.6 W, a maximum slope efficiency of 45%, and a single-lobed spatial mode.
