Abstract

One- and two-photon pumped random lasing have been demonstrated in a powder based on a Rhodamine B-doped diureasil hybrid by using a picosecond pump laser emitting either at 532 nm or 1064 nm under controlled experimental conditions. In both cases, we have used the same diffusive medium with identical spatial disorder, the same time-width and temporal profile for the pump pulse, as well as equal pump spot sizes. The corresponding onsets of laser-like emission and slope efficiencies are also investigated.
