Abstract

Precise pulse shaping is vital for present and future high-power lasers that will attempt to achieve low-entropy laser-fusion implosions. Multichannel, streak-camera-based systems are used to make such measurements. Such systems must be accurately calibrated in order to correct for time-base and flat-field variations. We use an on-line calibration system in order to measure the sweep rate, and in our recent work we have evaluated the accuracy of this measurement technique. By analyzing a large number of calibrations, and the effect of noise on our measurement technique, we have concluded that the sweep rate for our streak camera systems is reproducible to at least ±1.2% and that our measurement technique contributes an additional ±0.5% uncertainity in the measurement.
