Abstract

We report a femtosecond optical parametric oscillator (OPO) based on the nonlinear material BiB3O6. The OPO is synchronously pumped in the blue by the second harmonic of a Kerr-lens-mode-locked Ti:sapphire laser. It can provide wide and continuous tuning across the entire green–yellow–orange–red spectral range with a single crystal and a single set of mirrors. Using a 500μm BiB3O6 crystal and collinear type I (e+eo) phase matching in the optical yz plane, a signal wavelength range of 480710nm is demonstrated with angle tuning at room temperature at average output powers of 270mW. With 220fs blue pump pulses, near-transform-limited signal pulses of 120fs duration have been obtained at 76MHz repetition rate.
