报道了半导体激光端面泵浦的Ｎｄ∶ＹＶＯ４激光器获得线偏振的１．０６４μｍ激光高效率连续稳定输出。在半导体激光功率为１．５Ｗ时，获得连续输出功率为８３７ｍＷ的ＴＥＭ００模，激光器泵浦阈值功率为１４０ｍＷ，斜率效率达６１．５％，光－光转换效率达５６％，电－光转换效率达１５％。

Laser diode end pumped Nd∶YVO 4 laser with high efficency 1.064 μm laser output is repoted. The CW laser output was TEM 00 mode linear polarization. Up to 837 mW of output power was obtained with 1.5 W pumping power on Nd∶YVO 4 crystal. Pumping threshold was 140 mW. The slope effieicny of the laser was 61.5% and total optical conversion efficiency was 56%. Electrical effieincy of 15% was obtained.
