Second harmonic generation at 399 nm resonant on the ${}^1{S}_0{-}^1{P}_1$ transition of ytterbium using a periodically poled LiNbO${}_3$ waveguide

Abstract

We demonstrate a compact and robust method for generating a 399-nm light resonant on the ${}^1{S}_0{-}^1{P}_1$ transition in ytterbium using a single-pass periodically poled LiNbO${}_3$ waveguide for second harmonic generation (SHG). The obtained output power at 399 nm was 25 mW when a 798-nm fundamental power of 380 mW was coupled to the waveguide. We observed no degradation of the SHG power for 13 hours with a low power of 6 mW. The obtained SHG light has been used as a seed light for injection locking, which provides sufficient power for laser cooling ytterbium.
