Tunable mid-infrared MHz-rate picosecond pulses generated by optical parametric amplification of white-light continuum in GaSe.
The output of a long-cavity 2 MHz all-solid-state Nd:YVO(4) picosecond oscillator with nonlinear optical mirror mode locking is used for direct pumping of an optical parametric amplifier seeded with white-light continuum generated in optical fiber by the same laser to generate tunable (5-12 microm) mid-IR radiation.
