ABSTRACT:
By using a polarization controller, a semiconductor laser apparatus oscillating in the transverse magnetic mode in mode-locked state is realized, and a short optical pulse is generated. By coupling this mode-locked semiconductor laser to a wavelength conversion element, a second harmonic wave is generated, and an even shorter optical pulse is obtained at a higher power.
