Spectral broadening and compression of femtosecond light pulses that pass through dye amplifiers.
The amplification of femtosecond light pulses in multistage as well as in traveling-wave dye amplifiers is studied numerically, taking into account group velocity dispersion, self-phase modulation that is due to Kerr-type nonlinearity, and gain depletion. The combined action of these processes results in a spectral broadening that can be utilized for pulse compression. The results are compared with experimental findings.
