Compressive inverse scattering using ultrashort pulses
Inverse scattering refers the retrieval of the unknown constitutive parameters from measured scattered wave fields, and has many applications such as ultrasound imaging, optics, T-ray imaging, radar, and etc. Two distinct imaging strategies have been commonly used: narrow band inverse scattering approaches using a large number of transmitters and receivers, or wideband imaging approaches with s...
متن کاملRaman amplification of ultrashort laser pulses in microcapillary plasmas.
Experimental evidences of Raman amplification of ultrashort pulses in microcapillary plasmas are presented. The amplification of 100-500 fs pulses was investigated in microcapillaries with different lengths. The experimental data, together with simulation results, indicate that the resonance condition for Raman amplification in high-density plasma, n(e) approximately 1-3x10(20) cm(-3), existed ...
متن کاملUltrashort Pulses
Ultrashort pulses usually are defined as those lasting less than a nanosecond. Low-energetic ultrashort pulses can be used, for instance, as a probe for studying the dynamics of ultrafast processes. Amplifying these pulses can deliver extremely high peak power, allowing applications such as laser particle acceleration, or γ-ray generation via Compton scattering on relativistic electrons. Existi...
متن کاملThomson scattering from ultrashort and ultraintense laser pulses.
The Thomson scattering in an ultraintense ( approximately 10(18) W cm(-2)) and ultrashort (20 fs) laser field is calculated that demonstrates different characteristics from those of the low-intensity field case. The electron trajectory no longer conforms to a figure-eight pattern, and the spectra demonstrate complex shifting and broadening to suggest that Thomson scattering can be used for char...
متن کاملEffect of Raman scattering on soliton interactions in optical fibers
We investigate numerically the effect of Raman scattering on the interaction of two temporally separated pulses with identical spectra that propagate inside a single-mode fiber as fundamental solitons. We take into account all interpulse Raman scattering terms in the generalized nonlinear Schrödinger equation and study the interplay between the Kerr, intrapulse Raman, and interpulse Raman effec...
