Resum
We report a quasi-phase-matched optical parametric oscillator that incorporates a chirped nonlinear crystal and uses prechirped pulses matched to the crystal chirp to improve the conversion efficiency and reduce the operational threshold. A 20-mm crystal of aperiodically poled KTiOPO4 is phase matched to stretched Ti:sapphire pump pulses. The Ti:sapphire laser produces 104-MHz output pulses at 850 nm that are stretched from 190 to 900 fs with an average output power of 750 mW. The system has dem...
