ABSTRACT:
Reflectors each having a reflectance peak wavelength within a band of the wavelength characteristics of a laser amplification factor in the unsaturated state of each light source for excitation are provided between light sources for excitation and an optical coupler, and stable wavelength locking is effected by returning a portion of a small portion of excited light reflected by the reflectors into the light sources for excited light.
