Generation of synchronized, independently tunable 120-fs light pulses with optical parametric oscillators.
We report the generation of powerful, widely tunable femtosecond radiation by parallel synchronous pumping of two singly resonant optical parametric oscillators with an additive-pulse mode-locked Nd:glass laser. For a single-pulse energy of 10 nJ, a tuning range of 0.9-1.5 microm is achieved with pulse durations of 120 +/- 20 and 200 +/- 20 fs. The time jitter is estimated to be +/-50 fs.
