利用1064 ~ 532 nm的双共振和频，在外腔中获得了186 mW的波长为355 nm的连续紫外光输出，总输入功率的转换效率超过20%。谐振器反射镜由1064和532 nm光束共享，从而在两个谐振模式之间产生最佳模式重叠。为了保持同时共振，我们将外谐振腔锁定到单频绿色激光，并将1064 nm激光锁定到谐振腔。这种技术可以应用于任何两个波长的连续和频或差频混频。
Using doubly resonant sum-frequency mixing between 1064 and 532 nm in an external resonator, we obtained 186 mW of continuous-wave ultraviolet output at λ = 355 nm with more than 20% conversion efficiency from the total incident power onto the mixing cavity. The resonator mirrors are shared by both the 1064- and the 532-nm beams, yielding an optimum mode overlap between the two resonating modes. To maintain the simultaneous resonance, we locked the external resonator to the single-frequency green laser and locked the 1064-nm laser to the resonator. This technique can be applied to cw sum- or difference-frequency mixing of any two wavelengths.
