Abstract

PURPOSE:To stabilize oscillation wavelengths by applying part of the laser light generated from a semiconductor laser diode to a diffraction grating, directing the diffracted light to a detector composed of plural elements, detecting the deviation between the element of the maximum sensitivity and the element in the position corresponding to a standard wavelength, and performing automatic control so that this deviation becomes zero.
