Nonstationary Regime of Random Lasers
arXiv:1011.5902 · doi:10.1103/PhysRevA.84.023826
Abstract
A numerical study is presented of one-dimensional and two-dimensional random lasers as a function of the pumping rate above the threshold for lasing. Depending on the leakiness of the cavity modes, we observe that the stationary lasing regime becomes unstable above a second threshold. Coherent instabilities are observed as self pulsation of the total output intensity, population inversion, and polarization.
