Generation of above 1010 Temporal Contrast,above 10~(20) W/cm~2 Peak Intensity Pulses at a 10 Hz Repetition Rate using an OPCPA Preamplifier in a Double CPA, Ti:sapphire Laser System

摘要

We demonstrate the generation of greater than 1010 temporal contrast with over 1020 W/cm~2 peak intensity pulses at a 10 Hz repetition rate from a Ti:sapphire chirped-pulse amplification (CPA) laser system utilizing double CPA, optical parametric chirped-pulse amplification (OPCPA), and cryogenic-cooling techniques. We also successfully produce uncompressed output pulse energy exceeding 30 J, indicating potential for peak power at the 500 TW level.
