ABSTRACT:
Ultrashort optical pulses of a high peak output are generated by gain-switching of a semiconductor laser possessing a current non-injection region with short current pulses. By coupling this semiconductor laser to a wavelength conversion element, a second harmonic wave is generated, and ultrashort optical pulses of a short wavelength and a high peak output are generated.
