High average power 200 fs mid-infrared KTP optical parametric oscillator tunable from 2.61 to 3.84 μm

We report a broadly tunable mid-infrared femtosecond KTiOPO 4 optical parametric oscillator (OPO) pumped by a mode-locked Yb:KGW oscillator. Under pump power of 7 W, up to 2.05 W average power was generated in the 1.41–1.71 μm region at a repetition rate of 151 MHz, corresponding to a pump-to-signal...
