Amplified spontaneous emission power and contrast ratio in a linear miltipass Ti:sapphire regenerative amplifier with a wavelength centered at 1054 nm are calculated and measured. It is shown that the passive losses of a seed pulse and the losses in coupling to the regenerative amplifier cavity mode degrade the intensity contrast ratio to 10(-6)-10(-7). The advantage of an optical parametric chirped pulse amplifier with respect to the contrast ratio is discussed.

Theoretically, Raman-like soliton compression of mJ, 30-fs pulses is predicted. Initial experiments demonstrate 2 times compression of 1.3 TW/cm2 pulses under non-optimal conditions. The results agree closely with numerical simulations.

A new concept - chirped-pulse cascade-compression - is proposed and demonstrated. Initial experiments agree with numerical simulations, including compression of 35 fs, 1.2 mJ-pulses to 20 fs. Scaling to higher pulse energies and compression ratios will be possible.

Because electrostatic fields in a plasma wave (E > 100 GV/m) can exceed those in conventional RF linacs, plasma - based accelerators can potentially offer a compact method for accelerating high energy electrons.

Summary form only given. High peak-power lasers, using the chirped pulse amplification (CPA) technique, now routinely achieve the terawatt level and generate focused intensities in the 10/sup 18/-10/sup 19/ W/cm/sup 2/ range. For many laser-matter interaction experiments, especially those involving solid targets, a high peak-to-background contrast, a high intensity and a well-characterized focal spot are necessary. During the amplification process, wave front distortions appear due mainly to thermal effects in the amplification media and imperfections of large optics. These distortions lead to a broader focus spot and a loss in terms of focused intensity. Amplified Spontaneous Emission (ASE) limits the pulse contrast in CPA lasers. By combining wave front correction, high aperture parabola and second harmonic generation we obtain a high-contrast beam with a high focused intensity.

The temporal envelope of plasma density oscillations in the wake of an intense (I∼4×1018 W/cm2, λ=1 μm) laser pulse (400 fs) is measured using forward Thomson scattering from a copropagating, frequency doubled probe pulse. The wakefield oscillations in a fully ionized helium plasma (ne=3×1019 cm−3) are observed to reach maximum amplitude (δne/ne∼0.1) 300 fs after the pump pulse. The wakefield growth (4 ps−1) and decay (1.9 ps−1) rates are consistent with the forward Raman scattering instability and beam loading, respectively.
