Abstract: | The emission spectrum of an injection GaAs laser having a quadrilateral cavity with a 13×13 mm square cross section and with a high pumping level is considered. Anomalously high dispersion revealed for the refractive index for the short-wave mode (ñ>7) and disappearance of dispersion for the long-wave (ñ=3.4) mode indicate in all probability the emergence of a gap in the electron energy spectrum at the wavelength of the fundamental lasing mode. In contrast to [1], the entire long-wave part of the spectrum is emitted coherently at the same frequency and probably without absorption. |
