“…Also in these simulations we have increased the initial value of L c by 2 to account for the longer optical path for harmonics which are observed off the target normal direction. Note that magnetic fields in the interior of the target due to the hot electron current may also induce ellipticity in the polarization of light through the Cotton-Mouton effect [23]. This was observed previously in the harmonic spectrum on the front side of the targets [24] and may also be the cause of the observed s component in the transmitted harmonics.…”

Experiments were performed in which intense laser pulses (up to 9x10(19) W/cm(2)) were used to irradiate very thin (submicron) mass-limited aluminum foil targets. Such interactions generated high-order harmonic radiation (greater than the 25th order) which was detected at the rear of the target and which was significantly broadened, modulated, and depolarized because of passage through the dense relativistic plasma. The spectral modifications are shown to be due to the laser absorption into hot electrons and the subsequent sharply increasing relativistic electron component within the dense plasma.

“…Therefore, one can come to the conclusion that relativistic effects of electrons and strong turbulence field are in favor of the generation of localized strong magnetic field. At the critical surface in laser-plasma, the beating of the incident and reflected laser wave produces strong transverse turbulence and heats the plasma to a high effective temperature [21,22], that is the reason why the largest magnetic fields are found near the critical surface [23,24].…”

The behavior of magnetic fields generated by high frequency transverse plasmons in relativistic plasmas can be described by a set of nonlinear coupling equations, which has considered the nonlinear wave-wave, waveparticle interactions and the relativistic effects of electrons. Modulational instability of the spontaneous magnetic fields is investigated on the basis of the nonlinear coupling equations. Analytical and numerical results indicate the self-generated magnetic fields are modulationally unstable and will be localized in a narrow region. The characteristic scale and maximum growth rate of the magnetic fields depend on the average Lorentz factor of electrons and the energy density of transverse plasmons. The relativistic effects of electrons will enhance the self-focusing of magnetic fields.

“…At relativistic intensities new phenomena have been observed, such as generation of Gigagauss magnetic fields [1] and of radiation pressures of few TBar. Therefore, the physical conditions observed in astrophysical objects like stellar nuclei can be created in the laboratory, using a compact laser system, which is affordable by a university.…”

A high power laser system called 'ATTILA' (Almost- Table Top Terawatt Intense Laser) (10 TW) is under development at the University of Milano, Bicocca. Once fully functional ATTILA will produce 10 J, 1 picosecond pulses, reaching the power of 10 TW. The system is based on the chirped pulsed amplification technique and uses Nd:glass single-pass amplification.The amplifier chain can be injected with two different oscillators: a Nd:YLF oscillator by Quantronix, stretched by an optical fiber, and a Nd:glass femtosecond oscillator by TimeBandwidth (Zurich), stretched by diffraction gratings, both delivering nanojoules pulses. A regenerative amplifier increasing the energy up to 1 mJ follows these.Recently, we have implemented an automatic control system for the stabilization of mode-locking in the Quantronix oscillator. This is based on the active control of cavity length and on accurate stabilization of mode-locker temperature. A PC using LabView software drives the system. We are now beginning the installation of an adaptive optics system with a deformable mirror in order to optimize the optical quality and focusability of the beam.Our final goal is to obtain an intensity of 10 18 W/cm 2 on target. This will allow the production of relativistic electrons and energetic protons, and the study of relativistic plasma physics and of matter in extreme conditions.
