Abstract

Laser beam profiling can quantify various aspects of a laser beam, such as its diameter, intensity, or divergence. For larger beams, this can be done using a lens-less camera; however, when the beam's radius becomes smaller than the length of a pixel, a knife-edge measurement is required to measure its width. This summer, I measured the waist of two lenses using this technique while also calibrating the motors used to find those waists with a Michelson Interferometer. The calibration was then used to determine the actual travel of the motors, thereby obtaining a more accurate measurement of the waists.
