Generation of optical solitons in the wavelength region 1.37–1.49 μm

First‐order soliton pulses of 77–250 fs duration have been generated in the wavelength region from 1.37 to 1.49 μm. These solitons are formed by transmitting dye laser pulses at 1.34 μm of 1 ps duration and peak intensity of ≊0.66 GW/cm2 through optical single mode fibers. Soliton narrowing and soliton self‐frequency shift are the dominant shaping mechanisms.
