Yb:fiber-laser-pumped high-energy picosecond optical parametric oscillator.
We report a high-energy extended-cavity MgO:PPLN optical parametric oscillator, synchronously-pumped by a femtosecond Yb:fiber laser. The oscillator operated at a signal wavelength of 1530 nm with a repetition-frequency of 15.3 MHz (9.8 m length) achieved using intracavity relay-imaging optics. The signal pulses had an average power above 1.0 W, durations of 1.5 ps and energies greater than 70 nJ, making it a potential source for rapid femtosecond waveguide inscription in infrared materials.
