Abstract.
We have successfully developed a laser system to produce pulses with a wavelength centered at 800 nm, energies above 15 J, temporally compressed to 75 fs and focused to power densities beyond 1021 W/cm2. Enabling technologies include chirped-pulse amplification (CPA), 10 cm aperture Ti:Al2O3 crystals, large diffraction gratings, and an energetic Nd:glass laser for pumping the final two amplifiers. Measurements of the compressed pulse spectrum, frequency resolved optical gating (FROG) diagnostic, and focal spot are presented. We have also investigated and developed a technique for suppression of transverse parasitic lasing in large-aperture Ti:sapphire crystal amplifiers.
