Abstract

Nondegenerate, two-beam coupling due to increasing absorption in Tm:YALO crystals at room temperature is reported. We measured the power-dependent nonlinear refractive index using a new technique. Also we explain the origin of this resonantly enhanced nonlinearity by cooperative dynamics involving pairs of coupled Tm ions in concentrated crystals.
