本文报道了GdxY 1-xCa 4 O（BO 3）3晶体在I型非临界相位匹配条件下的近紫外光产生。GdxY 1-xCa 4 O（BO 3）3也被应用于基于掺铒光纤放大器输出1547 nm的八次谐波的193 nm深紫外激光源，其中GdxY 1-xCa 4 O（BO 3）3（x = 0.68）用于387 nm的产生。使用这种紧凑的光源，5%的转换效率，从1547 nm的输入到193 nm的输出是在18千瓦的基本峰值功率实现。
We report on near-UV generation in GdxY1-xCa4O(BO3)3 crystals used under type-I non-critical phase-matching conditions. GdxY1-xCa4O(BO3)3 was also applied to a 193-nm deep-UV laser source based on the eighth harmonic of an erbium-doped fiber amplifier output at 1547 nm, in which GdxY1-xCa4O(BO3)3 (x = 0.68) was used for 387-nm generation. Using this compact light source, 5% conversion efficiency from the 1547-nm input to the 193-nm output was achieved at a fundamental peak power of 18 kW.
