【 摘 要 】

The Orion facility consists of two synchronized laser systems: two CPA (Chirped Pulse Amplification) beamlines each deliver 500J to target in a 0.5ps pulse (1PW) at 1054nm; and ten long pulse beamlines each deliver 500J in 0.1-5ns temporally shaped pulse at 351nm. One of the CPA beamlines has the option to be frequency doubled at sub-aperture to produce 100J laser pulses with a nanosecond contrast of ∼ 1014. Further work is under way to enhance the contrast of both CPA beamlines in the first harmonic.
