Electromagnetic bubbles: subcycle near-femtosecond and subfemtosecond field solitons
نویسندگان
چکیده
We demonstrate the feasibility of strong (up to atomic fields) and supershort (few-femtosecond or even subfemtosecond) subcycle (nonoscillating) electromagnetic solitons [EM bubbles (EMB’s)] in a gas of two-level atoms as well as EMB’s and preionization shock waves in classically nonlinear atoms. We show that EMB’s can be generated by existing sources of radiation, including subpicosecond half-cycle pulses and short laser pulses. We investigate how EMB characteristics are controlled by those of originating pulses. Our most recent results are focused on related transient phenomena, including EMB formation length, multibubble generation, and shocklike waves. © 1997 Optical Society of America [S0740-3224(97)03011-7]

متن کاملThree-dimensional relativistic electromagnetic subcycle solitons.
Three-dimensional (3D) relativistic electromagnetic subcycle solitons were observed in 3D particle-in-cell simulations of an intense short-laser-pulse propagation in an underdense plasma. Their structure resembles that of an oscillating electric dipole with a poloidal electric field and a toroidal magnetic field that oscillate in phase with the electron density with frequency below the Langmuir...
متن کاملSubfemtosecond pulses in the multicascade stimulated Raman scattering
We explore recently predicted multifrequency 2p solitons in multicascade stimulated Raman scattering (SRS) that was mode locked by the dynamics of population at a Raman quantum transition; we show that these solitons are eigensolitons of a general solitary-wave solution. Soliton components at each frequency are bright pulses of the same (Lorentzian) shape, in contrast to the familiar bright–dar...
متن کاملSubfemtosecond steering of hydrocarbon deprotonation through superposition of vibrational modes.
Subfemtosecond control of the breaking and making of chemical bonds in polyatomic molecules is poised to open new pathways for the laser-driven synthesis of chemical products. The break-up of the C-H bond in hydrocarbons is an ubiquitous process during laser-induced dissociation. While the yield of the deprotonation of hydrocarbons has been successfully manipulated in recent studies, full contr...
متن کاملSynthesized light transients.
Manipulation of electron dynamics calls for electromagnetic forces that can be confined to and controlled over sub-femtosecond time intervals. Tailored transients of light fields can provide these forces. We report on the generation of subcycle field transients spanning the infrared, visible, and ultraviolet frequency regimes with a 1.5-octave three-channel optical field synthesizer and their a...
