Laser-beam profiler and detector-surface scanner
Abstract
A portable, relatively inexpensive laser-beam profiler and detector-surface scanner was developed to map the intensity profile of laser beams and the cross-sectional response of optical detectors within a wavelength range of 633 nm to 10.6 micrometers. Equipment diagrams, circuit schematics, and examples of detector-response maps and laser-beam profiles are provided. Intensity distribution is an important parameter in obtaining good laser welds, and a knowledge of detector response is essential in determining the accuracy of laser power measurements.
