利用钛宝石激光器的四倍频特性，研制出了175~210ánm波长范围内可调谐的深紫外光激光器。利用KBBF晶体对倍频钛宝石激光器进行了直接二次谐波(SHG)倍频实验。最大输出功率在193ánm处为2.23ámW，从182ánm到210ánm的DUV激光输出功率大于1ámW。据我们所知，这是首次利用直接倍频技术实现了毫瓦级宽调谐DUV全固态激光器。
We have developed a widely tunable deep-ultraviolet (DUV) laser in the wavelength range from 175 to 210ánm by the fourth harmonic generation of Ti:Sapphire laser. The fourth harmonic generation is performed by direct second-harmonic generation (SHG) of a frequency doubled Ti:Sapphire laser with KBBF crystal. The highest output power is 2.23ámW at 193ánm, and the power of the DUV laser is more than 1ámW from 182ánm to 210ánm. To our knowledge, it is the first demonstration of milliwatt-level widely tunable DUV all-solid-state laser below 200ánm by direct SHG technique.
