We report on an efficient use of CsLiB6O10 (CLBO) crystals employed for an all-solid-state deep-UV laser system operated at 5 kHz. We obtained greater than 3 W of UV radiation around 242 nm by mixing the 349-nm third harmonic of a Nd:YLF laser with the tunable output from a Ti:sapphire laser in a CLBO crystal. This UV radiation was subsequently mixed with the residual 1047-nm output from the Nd:YLF laser in a second CLBO crystal. The system produced 1.5 W of deep-UV radiation at 196.3 nm, which is, to our knowledge, the highest deep-UV power below 200 nm generated in a nonlinear optical crystal. Additionally, the bandwidth of both outputs was estimated to be less than 200 MHz.
我们报告了一种高效利用CsLiB6O10（CLBO）晶体的方法，该晶体用于一个工作频率为5kHz的全固态深紫外激光系统。通过在CLBO晶体中将Nd:YLF激光的349nm三次谐波与钛宝石激光器的可调谐输出混合，我们在242nm附近获得了超过3W的紫外辐射。随后，该紫外辐射在第二个CLBO晶体中与Nd:YLF激光剩余的1047nm输出混合。该系统在196.3nm处产生了1.5W的深紫外辐射，据我们所知，这是在非线性光学晶体中产生的200nm以下最高的深紫外功率。此外，两个输出的带宽估计均小于200MHz。
