Compression of Stokes pulses generated through a parametric four-photon mixing process in a birefringent optical fiber

Opt Lett. 1989 Oct 1;14(19):1074-6. doi: 10.1364/ol.14.001074.

Abstract

We demonstrate the compressibility of Stokes pulses at a 1.075-microm wavelength that are generated through the parametric four-photon mixing process in a highly birefringent single-mode fiber pumped by 35-psec pulses at 1.053 microm from a cw mode-locked Nd:YLF laser. With a 300-m fiber and a grating pair the pump pulses at 1.053 microm are compressed to 350 fsec, with an average output power of 370 mW after compression. With a different input pump polarization angle and a different grating separation the Stokes pulses are compressed to 470 fsec, with the same average output power after compression.
