Lecture

Laser Spectrum Analysis

Description

This lecture explains two methods to measure a laser spectrum: using a grating-based optical spectrum analyzer and a Michelson interferometer. The Wiener-Khinchin theorem is introduced to relate autocorrelation functions and spectra, with practical examples and implications for single-sided spectral density.
