摘要：

A broadly tunable femtosecond optical parametric oscillator (OPO) based on KTiOPO4 that is externally pumped by a self-mode-locked Ti:sapphire laser is described. Continuous tuning is demonstrated from 1.22 to 1.37-mu-m in the signal branch and from 1.82 to 2.15-mu-m in the idler branch by using one set of OPO optics. The potential tuning range of the OPO is from 1.0 to 2.75-mu-m and requires three sets of mirrors and two crystals. Without prisms in the OPO cavity, 340 mW (475 mW) of chirped-pulse power is generated in the signal (idler) branch for 2.5 W of pump power. The total conversion efficiency as measured by the pump depletion is 55%. With prisms in the cavity, pulses of 135 fs are generated, which can be shortened to 75 fs by increasing the out
