Abstract

We report a front-end system that provides selection, stretching and amplification of 240 fs pulses from sub-nJ level up to 5 mJ with contrast ratio >10⁷. Laser system consists of a master oscillator GLX-200, single pulse selector, diffraction-grating stretcher, regenerative amplifier and electrooptical deflector. It is shown that spectral shaping reduces spectrum narrowing in amplifier . This system will be used for seeding a powerful CPA laser chain.
