Quick Shot

Seen in the upper left are four beamlines of OMEGA EP firing during a target shot. Riding along with those four beamlines is the 4ωprobe illuminated in its housing in the lower right and next to the grating compressor chamber. The green irradiation stems from the frequency conversion of the primary infrared beam to the second harmonic or 527 nm. Remotely triggered, the image was captured from the top of the target area structure with no bay lights on.
