Modifying Laser Beams: There’s No Way Around It, So Here’s How
In order to apply a laser to an industrial process, medical therapy, or communications technology, it is usually necessary to modify the laser beam to achieve the desired results. Laser beam measurement tools make this possible. Here's how to match the laser beam profiling technique to the application, from building an aligned optical system to collimating and focusing to proper attenuation techniques for accurate measurements.
