Evolution and Collapse of a Lorentz Beam in Kerr Medium
The effect of Kerr nonlinearity on a Lorentz beam is investigated by using the nonlinear Schrödinger (NLS) equation. Based on the variational method, the evolution of a Lorentz beam in a Kerr medium is demonstrated and the critical collapse powers of the Lorentz beam are derived. Numerical simulations of the propagation of a Lorentz beam in a Kerr medium show that the beam becomes quasicircular...
متن کاملConversion between triangular and rectangular Bézier patches
This paper presents an explicit formula that converts a triangular Bézier patch of degree n to a degenerate rectangular Bézier patch of degree n× n by reparametrization. Based on this formula, we develop a method for approximating a degenerate rectangular Bézier patch by three nondegenerate Bézier patches; more patches can be introduced by subdivision to meet a user-specified error tolerance. ...
متن کاملSpatial evolution of laser beam profiles in an SBS amplifier.
We have performed an experimental and theoretical analysis of the modification of the transverse structure of a probe beam on propagation through an SBS amplifier. The theoretical analysis is based on performing a mode decomposition of the incident fields and determining how each mode amplitude is modified as a result of the nonlinear coupling. For the case of input beams with Gaussian intensit...

15 صفحه اولElastic Initial and Post-local Buckling of Profiled through Girders
An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, ...
