Raman forward scattering of high-intensity chirped laser pulses
Raman forward scattering of a high-intensity, short-duration, frequency-chirped laser pulse propagating in an underdense plasma is examined. The growth of the direct forward scattered light is calculated for a laser pulse with a linear frequency chirp in various spatiotemporal regimes. This includes a previously undescribed regime of strongly-coupled four-wave nonresonant interaction, which is ...
متن کاملHigh-intensity double-pulse X-ray free-electron laser
The X-ray free-electron laser has opened a new era for photon science, improving the X-ray brightness by ten orders of magnitude over previously available sources. Similar to an optical laser, the spectral and temporal structure of the radiation pulses can be tailored to the specific needs of many experiments by accurately manipulating the lasing medium, that is, the electron beam. Here we repo...
متن کاملHigh-harmonic generation in plasmas from relativistic laser-electron scattering
Results are presented on the generation of high harmonics through the scattering of relativistic electrons from high-intensity laser light. The characteristic signatures of this process are found to be the emission of evenorder harmonics, linear dependence on the electron density, significant amount of harmonics with circular polarization, and small spatial extent of the source. The harmonics a...
متن کاملMeasurement of Forward Raman Scattering and Electron Acceleration from High-Intensity Laser–Plasma Interactions at 527 nm
High-intensity laser–plasma interaction experiments were performed using high-power laser pulses (greater than 8 TW) at a wavelength of 527 nm. These pulses were focused to intensity greater than 10 W/cm into underdense helium plasma at a density of 5 10 cm . Systematic examination of the forward Raman scattering instability was performed by measuring the spectrum of the forward scattered light...
متن کاملInteraction of Laser Beam and Gold Nanoparticles, Study of Scattering Intensity and the Effective Parameters
In this paper, the optical properties of gold nanoparticles investigated. For this purpose the scattering intensity of a laser beam incident on gold nanoparticles has been studied using Mie theory and their respective curves versus different parameters such as scattering angle, wavelength of the laser beam and the size of gold nanoparticles are plotted. Investigating and comparison of the depi...
