ABSTRACT:
A method of determining the dimensions of a laser beam spot, comprising: scanning the laser beam in a path across a reference-edge having a photodetector positioned therebehind; and measuring an output signal from the photodetector during the scanning, the output signal corresponding to an area of the laser beam spot incident on the photodetector during the scanning.A method of aligning a laser beam delivery system, the method comprising: positioning a measurement/alignment tool at a target location; firing the laser beam on the tool; observing the laser beam using the tool; and adjusting the system in response to the sensed laser beam.
