Laser manufacturers need to measure the spectra of continuous and pulsed lasers to determine properties. Often these measurements must be completed in a timescale of a few milliseconds to allow fast transient behavior to be captured. While each specific type of spectrometer has its advantages and disadvantages, we show in this article that cross-dispersion spectrometers are particularly well-suited to measuring a wide range of laser parameters.
