Homogeneous linewidth and linewidth enhancement factor for a GaAs semiconductor laser
Journal of Physics D: Applied Physics, 1986The homogeneous linewidth and the linewidth enhancement factor alpha for a room-temperature GaAs laser are studied, calculating the time constant for the relaxation of the polarisation. The homogeneous linewidth obtained, arising from electron-electron and electron-phonon interactions, is of the order of several meV.

Theory of vibrational linewidths
Chemical Physics Letters, 1976Abstract A simple theory of the homogeneous broadening of vibrational lines in the IR and Raman spectra of molecules in liquids is presented. The theory considers the relationship between the linewidth and excited state lifetime, parameters which may now be independently measured. It is used to qualitatively explain the dependence of the linewidth on

The contribution of quantum fluctuations of the electromagnetic-field amplitude and phase and the medium to the semiconductor laser linewidth is found. It is shown that this contribution increases the linewidth by an order of magnitude in comparison with the contribution of spontaneous radiation.

Multielement laser-diode linewidth theory
Optics Letters, 1988A simple formula is presented for the linewidth-power product of multielement laser diodes, under the condition that the active elements are submitted to the same field. The theory is particularly applicable to laser diodes incorporating two thin active layers of different composition.

In this paper are presented theoretical calculations of the linewidth of the Rayleigh phonon propagating along high symmetry directions of the (111) surfrace of Aluminium both for different temperatures and for different values of the phonon momentum.
