A tunable subpicosecond stimulated-Raman-scattering laser has been developed. In this laser the stimulated-Raman-active medium, with a broad gain line, is a single-mode glass optical fiber. During synchronous pumping of the laser by a cw Nd:YAG laser with active mode locking (rp = 60 ps), pulses 400-500 fs long have been obtained over the tuning spectral interval 1.076-1.12/лп. In addition, lasing at higher Stokes components and a spectral tuning of the laser have been achieved.
