K ₃ B ₆ O ₁₀ Cl (KBOC ) ，新非线性的光晶体，为产生的表演潜力优点深紫外(紫外) 与另外的硼酸盐晶体相比轻。在这份报纸，我们第一次与这晶体学习一个 femtosecond Ti:sapphire 放大器的第二泛音代(SHG ) 。激光力量被获得象在有 1-mm-long 晶体的 396 nm 的中央波长的 220 mW 一样高，并且最大的 SHG 变换效率到达 39.3% 。典型脉搏持续时间是 83 fs。结果显示出那第二泛音(嘘) 变换效率有这个房间进一步被改善并且新非线性的水晶很被适合产生高效率在 266 nm 下面的深紫外的激光放射。

英文摘要：

K3B6O10Cl （KBOC）, a new nonlinear optical crystal, shows potential advantages for the generation of deep ultraviolet （UV） light compared with other borate crystals. In this paper we study for the first time the second harmonic generation （SHG） of a femtosecond Ti：sapphire amplifier with this crystal. Laser power is obtained to be as high as 220 mW at the central wavelength of 396 nm with a 1-mm-long crystal, and the maximum SHG conversion efficiency reaches 39.3%. The typical pulse duration is 83 fs, The results show that second harmonic （SH） conversion efficiency has the room to be further improved and that the new nonlinear crystal is very suited to generate the high efficiency deep ultraviolet laser radiation below 266 nm.
