We demonstrate that the above-threshold behavior of a laser can be strongly affected by exceptional points which are induced by pumping the laser nonuniformly. At these singularities, the eigenstatesâ€¦ (More)

We show that Steady-state Ab initio Laser Theory (SALT) can be applied to find the stationary multimode lasing properties of an N-level laser. This is achieved by mapping the N-level rate equationsâ€¦ (More)

The spatial coherence of laser sources has limited their application to parallel imaging and projection due to coherent artifacts, such as speckle. In contrast, traditional incoherent light sources,â€¦ (More)

We investigate the properties of two-dimensional parity-time symmetric periodic systems whose non-Hermitian periodicity is an integer multiple of the underlying Hermitian system's periodicity. Thisâ€¦ (More)

We derive and test a generalization of the steady-state ab initio laser theory (SALT) to treat complex gain media. The generalized theory (C-SALT) is able to treat atomic and molecular gain mediaâ€¦ (More)

We introduce a general set of conditions for observing reverse pump dependence in lasers and other counterintuitive phenomena, which demonstrate that any irreducible system with patterned gain andâ€¦ (More)

We perform a first-principles calculation of the quantum-limited laser linewidth, testing the predictions of recently developed theories of the laser linewidth based on fluctuations about the knownâ€¦ (More)

We demonstrate that due to strong modal interactions through cross-gain saturation, the onset of a new lasing mode can switch off an existing mode via a negative power slope. In this process ofâ€¦ (More)

In this talk we discuss two novel effects in steady state microlasers. The first one is interaction-induced mode switching (IMS), where the onset of a new lasing mode switches off an existing modeâ€¦ (More)
