Course: Learn Laser Interferometry


3 Gaussian beams

3.2 Photodetectors


Here, we learn how to use photodetectors that take the spatial distribution of the beam into accout. Particularly, split photodetectors are useful for sensing the misalignment of a Guassian beam by subtracting the signals detected at the two segments of the photodetector.
