AI Article Synopsis
- The experiment focused on how modes behave within a porous gallium phosphide random laser, observing the shift from single-mode to multimode behavior.
- The high index contrast of the system makes it ideal for studying random lasers and we noted that, in the multimode regime, the modes compete with each other.
- Additionally, our analysis of the emission spectra revealed a specific pattern in the spacing of spectral modes, consistent with the level repulsion described by random-matrix theory's Gaussian orthogonal ensemble.
Article Abstract
We have experimentally studied the distribution of the spatial extent of modes and the crossover from essentially single-mode to distinctly multimode behavior inside a porous gallium phosphide random laser. This system serves as a paragon for random lasers due to its exemplary high index contrast. In the multimode regime, we observed mode competition. We have measured the distribution of spectral mode spacings in our emission spectra and found level repulsion that is well described by the Gaussian orthogonal ensemble of random-matrix theory.
