Four-wave mixing dipole soliton in laser-induced atomic gratings.
We demonstrate a novel type of stable multicomponent vector solitons consisting of two perpendicular four-wave mixing (FWM) dipole components induced by electromagnetically induced gratings. We analyze the formation and steering of the steady dipole solitons and their dynamical (energy transfer) effects. The dipole-mode solitons of two FWM processes have horizontal and vertical orientations, re...
متن کاملAdiabatic soliton laser.
The key to generating stable optical pulses is mastery of nonlinear light dynamics in laser resonators. Modern techniques to control the buildup of laser pulses are based on nonlinear science and include classical solitons, dissipative solitons, parabolic pulses (similaritons) and various modifications and blending of these methods. Fiber lasers offer remarkable opportunities to apply one-dimen...
متن کاملShaping an ultracold atomic soliton in a travelling wave laser beam
An ultracold wave packet of bosonic atoms loaded into a travelling laser wave may form a manyatom soliton. This is disturbed by a homogeneous force field, for example by the inevitable gravitation. The wave packet is accelerated and therefore the laser frequency appears to be chirped in the rest frame of the atoms. We derive the effective nonlinear Schrödinger equation. It shows a time dependen...
متن کاملاثربخشی لیزر Pulsed dye laser (PDL) در درمان گزانتلاسمای پلک
Background and Aim: Xanthelasma is a benign condition considered which is mainly as a cosmetic problem. There are many destructive treatment options that may result in scar formation and dyspigmentation such as cryotherapy and electro-cauthery. According to these side effects finding a non-invasive solution could be important. At this study we aimed to evaluate the effect of PDL laser in the t...
متن کاملDispersion-mode pulsed laser.
A new self-consistency condition in pulsed lasers with strong intracavity dispersion imposes dispersion modes with specific cavity-length dependent pulse rates, utilizing pulse-train self-imaging properties of a temporal Talbot effect. We give an experimental demonstration of such a laser operation, using a long fiber cavity. We also demonstrate temporal Talbot imaging of a train of short pulse...
