Description/Abstract
Photon avalanche mechanism results from a cross relaxation energy transfer induced build up of population in an intermediate metastable level without resonant Ground State Absorption (GSA). From this level a resonant absorption occurs to populate a higher level The main characteristics of such process is a power threshold which corresponds to a sudden increase of the fluorescence arising from the upper excited state as well as a slowing and a change of the rise shape of the transient signals
