Abstract(in English) We have already reported the oscillation wavelength shift of GaAlAs laser diodes in a magnetic field at room temperature.In this work,we confirmed the reproducibility of the dependence of the wavelength shift on the angle between directions of the magnetic field and the semiconductor laser.In order to investigate the cause of the error observed in the experiment by now,we measured the time dependence of the oscillation wavelength shiftafter we applied the magnetic field.We also measured the output laser power change in a magnetic field.Here,we discuss the mechanism of this wavelength shift by using our experimental results.
