Multimode-Eigenschaften verschiedener Halbleiterlasermodelle. I

Abstract

An equation for the intensities and frequencies of laser modes is given for general optical transitions between bands. The models of transitions with and without anyK-selection rule are treated as special cases. With the assumption that the emission band for transitions withK-selection is inhomogeneously broadened a mutual influence of two laser modes is found which is similar to that of a conventional laser with an inhomogeneous line. For the model of no selection rule the intensity of one laser mode is calculated for a given inversion. The lack of a selection rule produces a homogenisation. It is shown that this effect highly favours the single mode operation for running modes.
