A 10-W laser-diode bar, a multistripe monolithic laser-diode array, has been used to end pump Nd:YAG. Twelve beams emitted from 12 stripes, spaced 800 µm apart, of a 1-cm linear diode array were collimated with a multiprism array consisting of 14 prismlets with 800-µm width to pump the Nd:YAG facet. The maximum Nd:YAG cw output power at 1064 nm of 3 W was obtained at 10-W laser-diode-bar power with a slope efficiency of 35%, and a TEM(00) spatial mode with values of beam-quality factor M(2) of 1.29 and 1.76 in the planes perpendicular and parallel to the junction, respectively. A pulse width of 25.2 ns (1-kHz repetition) was obtained in acousto-optic Q-switched operation.
一个10瓦的激光二极管条，即一种多条纹单片激光二极管阵列，已被用于端面泵浦Nd:YAG。从一个1厘米长的线性二极管阵列的12个条纹发出的12束光，条纹间距为800微米，通过一个由14个宽度为800微米的小棱镜组成的多棱镜阵列进行准直，以泵浦Nd:YAG的小面。在10瓦激光二极管条功率下，获得了1064纳米处3瓦的最大Nd:YAG连续输出功率，斜率效率为35%，在垂直于和平行于结的平面上，TEM(00)空间模式的光束质量因子M(2)值分别为1.29和1.76。在声光调Q操作中获得了25.2纳秒（1千赫兹重复频率）的脉冲宽度。
