We demonstrate a high-power two-color femtosecond near-infrared optical parametric oscillator synchronously pumped by a 7:4W femtosecond Yb:KGW laser. This system is almost gap-free tunable with signal wavelengths ranging between 1445 and 1880nm, with up to 1:7W average signal output power at femtosecond pulse durations. At wavelengths near the point at which the cavity group-delay dispersion equals zero, dual-signal-wavelength operation occurs due to equal group delay at two wavelengths.
