  ABSTRACT: LFEX is a high-energy PW laser aiming for an output of 10 kJ/l-10 ps. In this paper the architecture of multi-pass chirped pulse amplifier with 2x2 arrayed structure, newly designed diamond-shape pulse compressor, pulse shaping technique and other technological developments are reported.

  ABSTRACT: A 10-kJ PW laser (LFEX) is under construction for the FIREX-I program. This paper reports a design overview of LFEX, the technological development of a large-aperture 2x2 arrayed amplifier with modified four-pass architecture, wavefront correction, a large-aperture Faraday rotator with a superconducting magnet, a new pulse compressor arrangement, and focus control. The activation of front-end and amplifier subsystems is being carried for narrow-band and broad-band (chirped pulse amplification) operations. The installation of optics and mechanics of pulse compressor and focusing subsystems will be finished by March 2008, and the partial operation will start in 2007.
