要約(英語): Recently, external enhancement cavities have been employed for the improvement of the conversion efficiency in various wavelength conversions. Indeed, the external enhancement cavities are very attractive because they are constructed without any sophisticated optical configuration and therefore we have expected that they are so applicable in the enhancement of the fundamental lights as to be utilized with a variety of light sources. In this study, we demonstrated the second harmonic generations (SHGs) of both an infrared continuous wave (CW) light and a mode-locked picosecond pulsed light in a similar external enhancement cavity with the same BiB3O6 (BiBO). Then we confirmed the enhancement effects for both lights. The maximum output power of the CW second harmonic light was 430mW and then the conversion efficiency was 54%. On the other hand, the maximum output power of the picosecond pulsed second harmonic light was 560mW and then the conversion efficiency was 70%. These values are excellent results in SHG with BiBO crystal in spite of the relatively low fundamental power. From the SHG output characteristics, we performed comparison of the optimization conditions of both external enhancement cavities and the characteristics of the enhancement effects.
