How to Profile Very Short Pulsed Laser Beams

A laser beam profiler is more or less a specialized camera rigged to measure beam width, divergence, and other qualities of the laser’s spatial intensity distribution. So, like any camera, it has a trigger which takes a given amount of time to open the shutter. Let’s say for argument’s sake that it take only 10μs…
