WebThe function I (ν) in the vicinity of ν0 is called the line profile (Fig. 3.1). The frequency interval δν = ν2 − ν1 between the two frequencies ν1 and ν2 for which I (ν1) = I (ν2) = I (ν0) /2 is the full-width at half-maximum of the line (FWHM), often shortened to the linewidth or halfwidth of the spectral line. Webthe linewidth (FWHM) is proportional to the square of the resonator bandwidth divided by the output power (assuming that there are no parasitic resonator losses).
