1.3-2.0 /spl mu/m widely wavelength tunable compact ultrashort pulse source using optical fibers

Summary form only given. Using two types of optical fibers and Er-doped fiber laser, widely wavelength tunable ultrashort pulses are generated from 1.32-2.03 /spl mu/m. In addition to the Stokes pulse, the anti-Stokes pulse which is shifted toward the shorter wavelength side is also generated. In the experiment, the passively modelocked Er-doped fiber laser (IMRA Femtolite 780 Model FA1550) is used as the pump light source. It generates 110 fs optical pulses at a wavelength of 1.56 /spl mu/m.
