Paper Abstract

We present a conceptual design of multi-PW ultrashort laser system based on existing large-aperture Nd:glass laser facility. Compared with current PW laser, innovative technologies are adopted in the design, which includes large-aperture OPA to generate 10mJ femtosecond laser at 1 μmicron directly, high energy OPCPA preamplifier up to 1 J-level and chirped pulse shaping by AOPDF. To simulate the multi-PW CPA precisely, we build up an amplification model that can treat either homogenous broadening or inhomogenous gain media. As a first phase of our multi-PW laser, we are now constructing an ultrashort laser system that can produce pulse energy > 100 J with pulse duration of 350 fs.
