Abstract

This work presents an accurate experimental comparison among the spectro-temporal performances of near infrared and visible emitting solid state random lasers under ultrafast pumping. The near infrared random lasers are based on stoichiometric Nd crystal powders whereas the visible random laser is a ground powder of a hybrid compound based on Rhodamine B incorporated into a di-ureasil host. We demonstrate that despite the different nature of the base materials, the spectro-temporal dynamics of both kind of systems can be described by a rate-equations model based on the photon paths in an amplifying medium with an exponential probability distribution.
