Abstract
The present invention relates to a method of enabling generation of pulsed lights each having a narrow pulse width and high effective pulse energys. A pulse light source has a MOPA structure, and comprises a single semiconductor laser, a bandpass filter and an optical fiber amplifier. The single semiconductor laser outputs two or more pulsed lights separated by a predetermined interval, for each period given according to a predetermined repetition frequency. The bandpass filter attenuates one of the shorter wavelength side and the longer wavelength side, in the wavelength band of input pulsed lights.
