Abstract: Abstract This paper presents a novel method for high-precision narrow laser linewidth measurement through demodulating the coherent envelope of the short delayed self-heterodyne interferometry spectrum. Our method based on short delayed self-heterodyne interferometry can ignore… read more here.

Abstract: We propose a precision measurement method of laser linewidth based on short-delay self-homodyne, using the second peak-valley difference (SPVD) feature of the coherent power spectrum to fit laser linewidth. The SPVD model of the self-homodyne… read more here.
