Title: A method for stabilising an air-spaced Fabry-Perot etalon
Abstract: A simple method is described for stabilising the optical thickness of the air gap in a piezoelectric Fabry-Perot etalon. The spacing between the plates is controlled by an error signal proportional to the difference in intensity of two orthogonally polarised modes of a frequency stabilised He-Ne laser.
