Abstract :
Time-resolved spectra of an internal

-switching emission of electron-beam-excited GaAs lasers were measured. The spectra shifted to longer wavelengths at the rate of 5.63 Å/ns at 85 K. Time-resolves spectra of a normal laser emission were also measured to be shifted to longer wavelengths at the rate of about 0.3 Å/ns. This remarkable difference of the spectral shifts can be understood if the former shift is caused by the quasi-Fermi level in the conduction band and the latter shift is caused by thermal effects.
