Pulse compression and shaping of broadband optical parametric amplifier laser source.
We report pulse compression and shaping of a 100 Hz broadband optical parametric amplifier (OPA) laser source generated by self-phase modulation in a hollow-core fiber. The amplitude and phase of the broadband OPA laser pulses are controlled using an acousto optic programmable dispersive filter (AOPDF). Using the AOPDF, we demonstrate compression, characterization, and amplitude/phase control of 1300 nm 20 fs laser pulses with energies up to 10 microJ. This novel source is suitable for seeding successive OPA amplification stages and for time-resolved spectroscopy.
