Weakly scattering random lasers exhibit lasing modes that spatially overlap and can interact strongly via gain saturation. Consequently, lasing in high-threshold modes may be suppressed by strong low-threshold lasing modes. We numerically examine the effect of inherent spontaneous emission noise on this strong nonlinear phenomenon. With a method to incorporate this noise into the Maxwell–Bloch equations for simulations of random lasers, emission below the lasing threshold is observed and the… 


Numerical study of amplified spontaneous emission and lasing in random media
We simulate the transition from amplified spontaneous emission (ASE) to lasing in random systems with varying degrees of mode overlap. This is accomplished by solving the stochastic Maxwell-Bloch
Effects of spatially nonuniform gain on lasing modes in weakly scattering random systems
A study on the effects of optical gain nonuniformly distributed in one-dimensional random systems is presented. It is demonstrated numerically that even without gain saturation and mode competition,
Strong Interactions in Multimode Random Lasers
It is shown that the modal interactions through the gain medium in such lasers are extremely strong and lead to a uniformly spaced frequency spectrum, in agreement with recent experimental observations.
Nonlinear effects in random lasers
Recent numerical and theoretical studies have demonstrated that the modes at threshold of a random laser are in direct correspondence with the resonances of the same system without gain, a feature
Modes of random lasers
In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, directivity, and polarization.
Mode repulsion and mode coupling in random lasers
We studied experimentally and theoretically the interaction of lasing modes in random media. When optical gain spectrum is inhomogeneously broadened, most lasing modes repel each other in the

By varying the amount of scattering in an amplifying random medium, the transition from amplified spontaneous emission to lasing with coherent feedback is observed by finding out when the transition occurs through the measurement of the scattering mean free path.
Lasing in random media
Abstract A random laser is a non-conventional laser whose feedback mechanism is based on disorder-induced light scattering. Depending on whether the feedback supplied by scattering is intensity
Statistical theory of multimode random lasers
We present a semiclassical laser theory for multimode lasing in optical resonators with overlapping modes. Nonlinear saturation and mode competition are characterized in terms of left and right
Photon-number correlations near the threshold of microcavity lasers in the weak-coupling regime.
The quantum-noise properties near the threshold of microcavity lasers are studied theoretically and experimentally in the weak-coupling regime and it is shown that there always exists a finite threshold for these lasers defined by the peak of the photon-number correlation function corresponding to the spontaneous-to-stimulated transition.
