Abstract
The pulse light source according to the present invention comprises: a seed pulse generatorfor outputting an input pulseas a seed pulse; a pulse amplifier; and a dispersion compensatorfor dispersion compensating a light pulse output from the pulse amplifier. Moreover, the pulse amplifiercomprises a normal dispersion medium (DCF) and an amplification medium (EDF) that are multistage-connected alternately, for changing the input pulseto a light pulse having a linear chirp and outputting the light pulse. Furthermore, an absolute value of the dispersion of the DCFbecomes to be larger than the absolute value of the dispersion of the EDF
