摘要
The design and performance of a passive plasma isolator for suppressing retropulses in high-power CO//2 laser-fusion systems are presented. The device uses a gas-filled spatial filter designed to produce a plasma at the focal plane iris. General design criteria for these isolators are discussed, and the performance of a specific isolator is evaluated. For the unit tested, retropulse attenuations of 33 dB for focal plane intensities of 1. 5 TW/cm**2 have been demonstrated.
