Paper Abstract

The output of a pulsed laser is generally monitored as a function of time. The spatial properties of the beam, when they are measured, are usually time integrated. A study which provides a time resolved view of the spatial properties can often yield valuable insight into the overall behavior of the system. For example, if a laser radiates from small areas of the rod which shift with time, the resulting spread of the beam is more directly associated with this area than the apparent area obtained from an integrated observation. Standard high-speed framing and streaking cameras can be used to study the output of the conventional pulsed lasers, since much useful information can be obtained with their microsecond resolution. When the laser is operated in the giant-pulse mode, the camera must have a temporal resolution better by several orders of magnitude. This improved resolution can only be accomplished through electronic or electro-optical techniques.
