X-ray radiation from nonlinear Thomson scattering of an intense femtosecond laser on relativistic electrons in a helium plasma.
We have generated x-ray radiation from the nonlinear Thomson scattering of a 30 fs/1.5 J laser beam on plasma electrons. A collimated x-ray radiation with a broad continuous spectrum peaked at 0.15 keV with a significant tail up to 2 keV has been observed. These characteristics are found to depend strongly on the laser strength parameter a(0). This radiative process is dominant for a(0) greater...
متن کاملFemtosecond Laser Filamentation in Air
Femtosecond laser filamentation was excited in air. Measurement of the length of the light filament formed was carried out, using calibration method with an analysis on the precision of the measurement. From the photoemission spectra obtained by optic spectrometer, valuable information on the mechanism of interaction of strong laser pulses with atoms and molecules could be obtained. Furthermore...
متن کاملExcited ions in intense femtosecond laser pulses: laser-induced recombination.
Electron-ion recombination in a laser-induced electron recollision is of fundamental importance as the underlying mechanism responsible for the generation of high-harmonic radiation and hence for the production of attosecond pulse trains in the extreme ultraviolet and soft x-ray spectral regions. By using an ion beam target, remotely prepared to be partially in long-lived excited states, the re...
متن کاملPolyatomic molecules under intense femtosecond laser irradiation.
Interaction of intense laser pulses with atoms and molecules is at the forefront of atomic, molecular, and optical physics. It is the gateway to powerful new tools that include above threshold ionization, high harmonic generation, electron diffraction, molecular tomography, and attosecond pulse generation. Intense laser pulses are ideal for probing and manipulating chemical bonding. Though the ...
