Stable, high-power, Yb-fiber-based, picosecond ultraviolet generation at 355 nm using BiB3O6

We report a stable, high-power, high-repetition-rate, picosecond ultraviolet (UV) source at 355 nm based on singlepass sum-frequency generation of a mode-locked Yb-fiber laser at 1064 nm in the nonlinear crystal BiB3O6. By performing single-pass second-harmonic generation (SHG) in a 30-mm-long LiB3O...
