Abstract
In computer simulations the population mechanisms of the room-temperature continuous-wave green up-conversion Er3+:LiYF4 laser are investigated. An avalanche process is the dominating excitation mechanism, but it also counteracts stimulated emission at higher dopant concentrations. This concentration dependence can be considered as a behaviour present in many rare-earth-doped avalanche lasers.
