Experimental studies on the mode structure of random lasers

Experimental studies on the mode structure of random lasers
We investigate the mode structure of a random laser consisting of a porous semiconductor matrix infiltrated with and surrounded by laser dye. The experimental parameters that influence the types of lasing that are observed are identified. The spatial structure of random laser modes is accessed experimentally by a spatially and spectrally selective detection scheme. We show that random laser modes are distinct from laser speckle.

Abstract

We investigate the mode structure of a random laser consisting of a porous semiconductor matrix infiltrated with and surrounded by laser dye. The experimental parameters that influence the types of lasing that are observed are identified. The spatial structure of random laser modes is accessed experimentally by a spatially and spectrally selective detection scheme. We show that random laser modes are distinct from laser speckle.
