We present the design of the 10 TW OPCPA system which is currently being constructed for the Laser and Attosecond Physics laboratory at the Max-Planck Institute for Quantum Optics and perform a detailed characterization of a newly developed picosecond pump source. The setup consists of a broadband femtosecond seed oscillator, three OPCPA stages and an independent 80-ps pump laser, whose repetition rate is actively synchronized to the repetition rate of a fs- oscillator. The pump laser is a Nd:YAG flash-lamp pumped system consisting of a Nd:YVO/sub 4/ based picosecond pulse oscillator, a regenerative amplifier, a two-pass pre-amplifier. and two power amplifiers. At the output system produces more than 1.4 J of 1064 nm in 90-ps pulses at a 10-Hz repetition rate. These pulses are frequency doubled in a DKDP crystal yielding about 700-mJ. 80-ps pulses at 532-nm with a multimode spatial profile and a nearly Gaussian temporal profile. The near-field pump beam profile is relay-imaged from the doubling crystal of the pump laser on each nonlinear crystal in order to have the best amplification efficiency.
