Optical pulse amplifier and optical pulse source

摘要

The pulse light source, according, to the present invention comprises: a seed pulse generator 1 for outputting an input pulse 10 as a seedpulse; a pulse amplifier 2; anda dispersion compensator 3 for dispersion compensating a light pulse output from the pulse amplifier 2. Moreover, the pulse amplifier 2 comprises a normal dispersion medium (DCF 4) and an amplification medium (EDF 5) that are multistage-connected alternately, for changing the input pulse 10 to a light pulse having a linear chirp and outputting the light pulse. Furthermore, an absolute value of the dispersion of the DCF 4 becomes to be larger than the absolute value of the dispersion of the EDF 5.
