Influence of the optical pumping power fluctuations on the OGRAN detector sensitivity

V.A. Krysanov1


We consider the radiophysical parameters of the Fabry-Perot interferometer with energy losses. Analytic expressions are presented, determining the expected sensitivity of a mechanical displacement meter for the interferometer. A new parameter, characterizing power fluctuations of laser emission, is introduced and experimentally found. The effect of these fluctuations on the measurement sensitivity in the presence of spurious amplitude modulation of the radiation is studied and estimated.
