英文摘要PURPOSE:To reduce the temperature dependency of an oscillating wavelength by providing a reflector oppositely to one emitting end face of a semiconductor crystal which contains a laser active region, inserting a substance which decreases its refractive index as the temperature rises between the crystal and the reflector, and mounting the reflector to shorten the interval between the crystal and the reflector as the temperature rises. CONSTITUTION:A dielectric multilayer 5 is coated to prevent reflection on one emitting end face of a laser crystal 1, an opticalwaveguide 10 of a dielectric is provided behind it, and a reflecting mirror 20 is provided at the end of the opposite side to the end coupled to the crystal 1 of the opticalwaveguide 10. In this structure, laser oscillating wavelength satisfies the relationship of nDLD+ nRLR=mlambda/2. However, the nD, nR respectively represent the effective refractive indexes in laser crystal and opticalwaveguide, and the LR is the length of the opticalwaveguide. Accordingly, the value of the temperature dependency of the oscillating length becomes 0 when the laser crystal is GaAs, the opticalwaveguide is polystyrene, the lengths are 300mum, 52mm., and even if the temperature is varied, a laser which does not vary in the oscillating length can be obtained.
