Abstract
Two-beam coupling measurements of an avalanche upconversion transition in concentrated Tm:LiYF4 confirm that, despite the resonant nature of the excited-state optical interaction, the induced response is strongly dispersive. This surprising characteristic is shown to be a general feature of avalanche polarization, with an off-resonant process dominating the resonant response.
