Page 6: Chapter 3 Description
Fabry-Perot Interferometer Chapter 3: Description Chapter 3 Description The SA210 is a high finesse Spectrum Analyzer used to examine the fine structures of the spectral characteristics of CW lasers. The spectrum analyzer consists of a confocal cavity that contains two high reflectivity mirrors; by varying the mirror separation with a piezoelectric transducer the cavity acts as a very narrow band-pass filter. -

Fabry-Perot Interferometer Chapter 4: Fabry-Perot Interferometry Chapter 4 Fabry-Perot Interferometry 4.1. Free Spectral Range To scan the spectra of the laser beam entering the Scanning Fabry–Perot interferometer small displacement is applied to one of the cavity mirror mounted on piezoelectric transducers. This operation is done by fine tuning the ramp voltage applied to the Piezoelectric elements using the controller SA201. -
