The theory of spatial pattern formation in a nonlinear cavity is extended to account for the vector nature of the fields. For a self-defocusing medium rolls (stripes) can form spontaneously under suitable conditions. The roll patterns exhibit many de

The spontaneous emergence of patterns beyond some critical value of an external stress parameter, is illustrated with three examples from nonlinear optics. Counterpropagating beam patterns in an extended optically transparent system pose a challengin

Counterpropagating laser beams can couple to acoustic phonons and cause efficient simultaneous generation of both Stokes and anti-Stokes fields. This results in a combination of dynamic oscillation and spontaneous transverse spatial symmetry breaking

Proceedings of 1994 Nonlinear Optics: Materials, Fundamentals and Applications.
A ring-cavity system, filled with an isotropic nonlinear medium and driven by a linearly polarized coherent input field, has been the subject of intense study over the last decade. This system can show a number of non-equilibrium phase transitions, i

Summary form only. It has recently been proposed that there is an interesting link between the dynamics of an actively mode-locked laser model and "transient gain", a proposed mechanism in fluid turbulence. We show that these results are considerably

Vacuum wall deposition of a-B/C films has had tremendous positive impact on the performance of tokamak fusion reactors. In the present work, sublimed gas from o-carborane and helium carrier gas are used to create a plasma using the surface-ECR source
