采用紫外截止波长为165 nm的硼酸钇铝[YAl(3)(BO(3))(4)] （YAB）晶体作为四次谐波非线性光学晶体。Nd:YVO(4)主振荡器功率放大器的1064 nm基频激光频率翻倍至532 nm。利用I型相匹配YAB晶体，在65 kHz脉冲重复频率下，获得了平均功率5.05 W的266 nm紫外激光器，从532到266 nm的转换效率为12.3%。实验结果表明，利用YAB作为非线性光学晶体产生高功率四次谐波具有很大的应用潜力。
A yttrium aluminum borate [YAl(3)(BO(3))(4)] (YAB) crystal with UV cutoff wavelength of 165 nm is used as the nonlinear optical crystal for fourth harmonic generation. The fundamental frequency laser at 1064 nm from an Nd:YVO(4) master oscillator power amplifier laser was frequency doubled to 532 nm. Using the type I phase-matching YAB crystal, a 5.05 W average power 266 nm UV laser was obtained at the pulse repetition frequency of 65 kHz, corresponding to the conversion efficiency of 12.3% from 532 to 266 nm. The experimental results show great potential for the application of using YAB as a nonlinear optical crystal to get high-power fourth harmonic generation.
