Passively mode-locked Yb:LuVO(4) oscillator.

Passive mode locking of the ytterbium doped orthovanadate crystal Yb:LuVO(4) is reported for the first time. We demonstrate what we believe to be the shortest pulses directly generated with an Yb-doped crystalline laser using a semiconductor saturable absorber. The pulses at 1036 nm have a duration as short as 58 fs for an average power of 85 mW.
