Spectro-polarimetric signature of a random laser
Abstract
We characterized the spectro-polarimetric emission properties of random lasers in the regime of strong scattering. The study involved the preparation of microstructured samples, which were shown to support very stable random laser modes in spectral location and intensity. We show that random lasing modes from such samples are highly polarized in statically random, but well-defined states that can be used as a unique sample identifier. Our findings reveal a strong dependency of the emission spectrum on the pump polarization and demonstrate how the spectro-polarimetric emission can be efficiently manipulated.
