title: Enhanced internal reflection from an exponential amplifying region.
abstract: The reflectance of a p-polarized wave from an interface between a transparent medium and an amplifying medium with an exponential gain profile is derived. Experimentally determined reflectance curves are in agreement with theory and show amplification in the vicinity of the critical angle.
