Nonlinear optics in relativistic plasmas.
We review our recent work on the various nonlinear optical processes that occur as an intense laser propagates through a relativistic plasma. These include the experimental observations of electron acceleration driven by laser-wakefield generation, relativistic self-focusing, waveguide formation and laser self-channeling.
متن کاملDevelopments in Relativistic Nonlinear Optics
We report recent results of experiments and simulations in the regime of peak laser intensities above 10 W/cm, including the following topics: (1) electron and proton acceleration to energies in excess of 10 MeV in well collimated beams; (2) use of laser chirp to control the growth of plasma waves and acceleration of electrons by the Raman instability; (3) all optical injection and acceleration...
متن کاملThe Nonlinear Optics of Plasmas
It is well known that plasmas exhibit many of the characteristics of a non-linear optical medium when intense electromagnetic waves are incident upon it. These include harmonic generation, simulated Brillouin and Raman scattering, degenerate and resonant four wave mixing, self-focusing and parametric amplification. In addition, plasmas demonstrate certain unique nonlinear phenomena such as nonl...
متن کاملWeakly nonlinear geometrical optics in plasmas
A geometrical optics method for solving wave propagation in dispersive weakly nonlinear, weakly inhomogeneous media is applied to plasmas. In the case that the dispersion is comparable to the nonlinearity, the method yields the expected soliton solutions. For strong dispersion, it is found that the amplitude has the same form as in the linear case except that it is multiplied by a slow varying ...
متن کاملNonlinear Optics in Relativistic Plasmas and Laser Wake Field Acceleration of Electrons
When a terawatt-peak-power laser beam is focused into a gas jet, an electron plasma wave, driven by forward Raman scattering, is observed to accelerate a naturally collimated beam of electrons to relativistic energies (up to 10(9) total electrons, with an energy distribution maximizing at 2 megaelectron volts, a transverse emittance as low as 1 millimeter-milliradian, and a field gradient of up...
