Transmission statistics in nonconservative disordered optical medium
Zhong Yuan Lai, Oleg Zaitsev
We determine the cumulants of electromagnetic energy transmitted through one-dimensional disordered medium with absorption or amplification. For this purpose we derive the Keldysh…
Nonlinear sigma model for optical media with linear absorption or gain
Zhong Yuan Lai, Oleg Zaitsev
In the framework of the Keldysh technique, we formulate the nonlinear sigma model for disordered optical media with linear absorption or gain. The effective action for fluctuations…
Gas lasers with wave-chaotic resonators
Oleg Zaitsev
Semiclassical multimode laser theory is extended to gas lasers with open two-dimensional resonators of arbitrary shape. The Doppler frequency shift of the linear-gain coefficient l…
Diagrammatic semiclassical laser theory
Oleg Zaitsev, Lev Deych
We derive semiclassical laser equations valid in all orders of nonlinearity. With the help of a diagrammatic representation, the perturbation series in powers of electric field can…
Recent developments in the theory of multimode random lasers
Oleg Zaitsev, Lev Deych
We review recent extensions of semiclassical multimode laser theory to open systems with overlapping resonances and inhomogeneous refractive index. An essential ingredient of the t…
Statistical properties of one-dimensional random lasers
Oleg Zaitsev, Lev Deych, Vladimir Shuvayev
Statistical properties of a laser based on a one-dimensional disordered superlattice open at one side are studied numerically. The passive normal modes of the system are determined…
