Over 100 μW of continuous-wave tunable ultraviolet radiation at 370 nm is generated by the sum-frequency mixing of radiation from two extended-cavity laser diodes having powers of 60 mW at 822 nm and 8 mW at 671 nm in a lithium iodate crystal. The crystal is placed in an external cavity that enhances the powers of two fundamental beams simultaneously by approximately 40. This light source is successfully applied to the laser cooling of trapped ytterbium ions.
通过在碘酸锂晶体中对两个扩展腔激光二极管发出的辐射进行和频混合,产生了超过100 μW的370 nm连续波可调谐紫外辐射。这两个激光二极管在822 nm处的功率为60 mW,在671 nm处的功率为8 mW。该晶体置于一个外腔中,该外腔可同时将两束基波的功率提高约40倍。这种光源已成功应用于俘获镱离子的激光冷却。
