Linewidth study of the frequency-modulated laser based on the delayed self-heterodyne scheme
Optics & Laser Technology, 2013Abstract We investigate the linewidth of the frequency-modulated laser (FML) by using the delayed self-heterodyne (DSH) method. We deduce the expression of the linewidth theoretically and arrive at the conclusion that the linewidth of the FML measured by DSH method is the convolution of the spectrum of the output of the heterodyne interferometer with

A loss-compensated recirculating delayed self-heterodyne interferometer (LC-RDSHI) for laser linewidth measurement is theoretically analyzed. An analytical result for the output spectrum of the LC-RDSHI is obtained. It is found that the spectrum from a LC-RDSHI is equivalent to a spectrum from a conventional delayed self-heterodyne interferometer with ...

Two separate cw lasers are locked through a common delayed self-heterodyne interferometer, based on error signal generation via RF mixing of the self-heterodyne signal at the two separate wavelengths.

2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2012
Laser linewidth measurement based on the delayed self-heterodyne interferometer using a Mach-Zehnder modulator (MZM) is proposed and demonstrated. Instead of the single-sideband modulation in an acousto-optic modulator (AOM), the proposed scheme is implemented using carrier-suppressed double sideband modulation in the MZM.
