The authors of this publication in Photonics Research demonstrated a high power, high repetition rate quickly tunable (100 nm/ms) non-collinear OPO, which is directly pumped by the third harmonic of an Yb-fiber laser. Due to the non-collinear phase matching scheme, the signal wavelength covers almost the entire visible spectral range from 440 to 720 nm by varying the cavity length only. The authors have achieved stable output pulses with power up to 452 mW at 1.4% RMS and duration down to 286 fs. Hopefully this achievement will expand many applications in spectroscopy, metrology, and quantum optics.
