Abstract: A method for measuring two components, Lorentzian and Gaussian, of the spectral line of radiation from single-frequency laser diodes is presented using a pair of scanning ring fiber interferometers with different lengths of ring resonators. Experimental results are presented that confirm the effectiveness of the approach.

Keywords: laser diode, single-frequency radiation, laser linewidth.
