Theory of Talbot lasers

Theory of nonlinear Talbot effect

The nonlinear Talbot effect, in which self-images are formed by generated parametric light from the nonlinear optical process, is presented in this paper. The comparison is made between the conventional Talbot effect and the newly observed nonlinear case. The essence of such nonlinear self-images is provided and future work on this effect is also discussed. The conceptional extension achieved h...

The Theory of Atom Lasers

An atom laser is a device which produces a bright, directed, and coherent beam of atoms. An ideal atom laser beam is a single frequency de Broglie matter wave, approximating a noiseless sinusoidal wave; in particular it will have a well defined frequency, phase, and amplitude. Quantum mechanically, such a wave is a mode of the quantised field, and the properties of brightness and well defined p...

Talbot 2016 : Equivariant homotopy theory and the Kervaire invariant

Talbot solitons.

We propose a new type of scalar wave-mixing optical solitons, Talbot solitons. The soliton consists of sinusoidal and uniform components that are mutually coherent and jointly trapped in one direction. The intensity structure of the soliton oscillates in the propagation direction as a result of the linear Talbot effect and periodic nonlinear energy exchange between the components. Talbot solito...
