One of the first methods used to measure the coherence of a laser was interferometry. A typical method to measure the laser linewidth is self-heterodyne interferometry. An alternative approach is the use of spectrometry. Webb27 juni 2024 · Normally, I would expect the frequency of the beat note to indicate the frequency difference between the two lasers, and little else; the information about the coherence (including the linewidth) will be encoded in the details of the oscillation (e.g. things like the contrast of the beat) but that depends on exactly what you're measuring. …

The linewidth of a laser, typically a single-frequency laser, is the width (typically the full width at half-maximum, FWHM) of its optical spectrum. Particularly in cases with 1/f frequency noise, a linewidth value alone may not be regarded as completely characterizing the phase noise. It is prudent to measure the whole
