Abstract
At the cascade SRS in the region of negative chromatic dispersion of a single mode fiber, 70-to 100-fs light pulses have been obtained. It is shown that a 70-fs multisoliton pulse in a single mode fiber breaks up into “color” solitons. Pulses of 18 fs have been formed by multisoliton compression. The pulse duration corresponds to about three optical cycles at the wavelength of 1.6 μm. From the results of the experiment, the relaxation time of the silica-glass electron nonlinearity is estimated to be 2 to 4 fs.Keywords
