Semiconductor laser device, semiconductor laser module, and semiconductor laser control method

摘要

There is provided a semiconductor laser device in which a light amplifier integrated excitation light source is obtained by forming on a n-InP substrate a semiconductor laser diode section that outputs laser light having a plurality of oscillation vertical modes that are below the threshold value at which stimulated Brillouin scattering is generated together with a light amplifier section that amplifies laser light generated in the semiconductor laser diode section and outputs it to the outside. As a result, wavelength stability is increased and the generation of kinks is prevented.
