摘　　要：We experimentally demonstrate a femtosecond optical parametric oscillator （OPO） synchronously pmnped by a home-made solid-state mode-locking Yb：YCOB laser, which is capable of laser pulse as short as 102 fs and average power of 620 mW at the central wavelength of 1052 nm. By using a periodically poled lithium niobate with tuning of the grating periods from 28.5 to 31.5μm as the nonlinear gain crystal, tunable femtosecond pulses from 1444 to 1683 nm are realized by conveniently adjusting the OPO cavity length with 76.8 MHz repetition rate. The maximum average output power is 152 mW at 1568 nm, corresponding to an idler power of 75 mW at 3197 nm as well as 36.6% total extraction efficiency.We experimentally demonstrate a femtosecond optical parametric oscillator （OPO） synchronously pmnped by a home-made solid-state mode-locking Yb：YCOB laser, which is capable of laser pulse as short as 102 fs and average power of 620 mW at the central wavelength of 1052 nm.
