2波長同時共振型のCW深紫外和周波発生における周波数精密制御

抄録

Novel fine frequency tuning of the deep-ultraviolet single-mode coherent light at 252 nm was investigated by changing the temperature of the β-BaB₂O₄ (BBO) in doubly resonant external cavity for the sum-frequency mixing of 373-nm light and 780-nm light. The temperature-dependant frequency tuning rate is 19.3 MHz/°C, which is fine enough to realize the laser cooling of neutral silicon atoms.
