Abstract We investigate the adiabatic enhanced compression of ultrashort pulses from a distributed feedback laser operated at 1550nm in fibers with slowly decreasing dispersion (FSDD). High-quality pulse compressions from 4.4ps down to 1.1ps in a 100m FSDD and from 4.4ps down to 830fs in a 500m FSDD are obtained. The Raman self-frequency shift of femtosecond pulse in the compression is observed. Theoretical analyses are in good agreement with experimental results.
