Transverse pattern dynamics in the output of a laser are studied by detailed numerical solutions of the full set of Maxwell-Bloch equations. The effects of different parameters on the behavior of the solutions are investigated. Our numerical results

The behavior of a CO 2 laser brought from below to above threshold and back by modulating the cavity losses, is studied experimentally and theoretically. It is shown that the usual delay of the switch-on is followed by an anticipation of the switch-o

Pulsations which spontaneously break the cylindrical symmetry of a laser cavity geometry and the simultaneous appearance of topological defects in the transverse intensity patterns lead from periodic and quasiperiodic behavior to chaos and turbulence

The collective atomic recoil laser has recently been proposed as a very efficient method for generation of high frequency radiation such as x-rays and gamma rays and has been described as sharing the properties of both atomic and free electron lasers

We show how a collection of noninverted two-level systems, under the action of a quasiresonant pump field, can produce an exponential amplification of a probe signal through the mechanism of a dynamical instability with spatial self-bunching in a way

Noise driven transients in single mode semiconductor, solid state, and molecular gas lasers after they are ``switched on'' have strong (nearly linear) correlations between the time at which the laser intensity becomes significantly different from zer

We consider a cylindrically symmetrical laser with spherical mirrors and describe the dynamics in terms of the competition among different Gauss-Laguerre modes of the cavity. In this paper we focus on the case in which the mode competition leads the

We analyze the simplest dynamical transverse patterns which appear in ${\mathrm{Na}}_{2}$ and ${\mathrm{CO}}_{2}$ lasers. The experimental values of the control parameters correspond closely to those considered in the theoretical study reported in th
