Paper Abstract

A stability criterion and growth rates are derived for filaments in a semiconductor optical amplifier with a cylindrically expanding beam. The instantaneous growth rates are the same as they would be for a collimated geometry, but the development of the filaments is slowed because the spatial frequency is changing as the beam expands.
