Abstract: In order to grow a GaAs.sub.1-x P.sub.x fixed-composition layer of excellent quality, which has a predetermined composition x, over a GaAs or GaP single crystal substrate, a varied-composition layer is formed between the substrate and the fixed-composition layer. The varied-composition layer comprises at least two varied-composition layer portions and at least one fixed-composition layer portion with a predetermined thickness that is formed between the varied-composition layer portions, whereby dislocations caused by lattice mismatch with the GaP substrate are settled in the varied-composition layer portions and recovered in the fixed-composition layer portion between the varied-composition layer portions, thereby minimizing the dislocations, and thus making it possible to obtain a GaAs.sub.1-x P.sub.x layer of excellent crystal quality, which has a predetermined composition x.

Abstract: A semiconductor laser HL has an external resonator including a reflector R which reflects the emitted laser beam back into the front facet of the laser. The light emitted from the rear facet of the laser falls on a photodiode PD which generates a signal s which is evaluated by an evaluation unit AE. By differentiation or other processing of the shapes of pulses in the signal s, it is possible to determine the direction of change of any of several operating parameters of the laser system, such as the length L between laser HL and reflector R, the tilt angle of reflector R with respect to the optical axis of the laser or the refractive index n of the medium in the space N defined between the laser and the reflector. For example, one can detect when gas G is fed into space N to change the medium from ordinary air to carbon dioxide, or the reverse.
