Beam Self - Focusing in the Presence of Small Normal
نویسندگان
چکیده
We present a new system of modulation equations that approximate the focusing of the nonlinear Schrr odinger equation in the presence of small normal time dispersion (TDNLS). Since the modulation equations are much easier for analysis and for numerical simulations, they can be used to get a general picture of the TDNLS focusing. Analytical and numerical agreement between the modulation equations and the TDNLS is established.

Study of non-linear interaction of circular laser pulse propagating through hot magnetized plasma in the presence of a planar magnetostatic wiggler
In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...

متن کاملSmall beam nonparaxiality arrests self-focusing of optical beams.
A new equation for self-focusing in the presence of small beam nonparaxiality is derived. Analysis of this equation shows that nonparaxiality remains small as the beam propagates. Nevertheless, nonparaxiality arrests self-focusing when the beam width becomes comparable to its wavelength. A series of focusing-defocusing cycles of decreasing magnitude follows, ending with a final defocusing stage...
متن کاملTransverse Vibration for Non-uniform Timoshenko Nano-beams
In this paper, Eringen’s nonlocal elasticity and Timoshenko beam theories are implemented to analyze the bending vibration for non-uniform nano-beams. The governing equations and the boundary conditions are derived using Hamilton’s principle. A Generalized Differential Quadrature Method (GDQM) is utilized for solving the governing equations of non-uniform Timoshenko nano-beam for pinned-pinned...
متن کاملA Note on Free Vibration of a Double-beam System with Nonlinear Elastic Inner Layer
In this note, small amplitude free vibration of a double-beam system in presence of inner layer nonlinearity is investigated. The nonlinearity is due to inner layer material and is not related to large amplitude vibration. At first, frequencies of a double-beam system with linear inner layer are studied and categorized as synchronous and asynchronous frequencies. It is revealed that the inner l...
