About this document
Gaussian Beam Measurement via Knife Edge by Dev Jariwala is a document available to read on EtoBox.
Gaussian beams can be described mathematically as a function of the beam waist, wavelength, and distance from the waist. The beam width increases with distance from the waist according to the Rayleigh range. The knife-edge measurement technique involves translating a knife edge through the beam and measuring the transmitted power. By fitting the data to an error function, the beam width can be determined at different distances, fully characterizing the Gaussian beam. Alternatively, a quicker method uses the
