高功率声光调Q红色激光输出是通过使用LiB(3)O(5) (LBO)晶体对波长为1.319微米的Nd:YAG激光器进行腔内倍频而获得的。在 5 kHz 和 250+/-10 ns (FWHM) 的脉冲宽度下，证明了 659.5 nm 处的 28 W 平均功率。 M2值的光束质量水平和垂直方向均为22+/-3。通过薄型YAG标准具对1.338μm操作的抑制，659.5 nm处红色激光输出功率的稳定性和转换效率均得到提高。红光的长期稳定性在23W输出200小时内优于1%。
High-power, acoustooptic Q-switched red laser output is obtained by intracavity frequency-doubling a Nd:YAG laser operating at wavelength of 1.319 microm with a LiB(3)O(5) (LBO) crystal. 28 W average power at 659.5 nm was demonstrated at 5 kHz and a pulse width of 250+/-10 ns (FWHM). The beam quality of M2 value is 22+/-3 in both horizontal and vertical directions. The conversion efficiency and the stability of the red laser output power at 659.5 nm were both improved through the suppression of 1.338 mum operation by means of a thin YAG etalon. The long-term stability of the red light is better than 1% at an output of 23 W during 200 hours.
