Query: Partial compensation of thermal noise in the fundamental mode of an
  optical cavity   Thermal noise of optical cavities limits the accuracy of many experiments on
precision laser spectroscopy and interferometry. The study of the physical
properties of this noise opens opportunities for the creation of more stable
cavities, reduction of phase noise of optical radiation, and performance of
accurate optical studies. The paper proposes a method of partial recording of
TEM00 mode thermal noise of a Fabry-Perot cavity using two "probe" modes of
higher order. The method allows partial compensation of noise in the
fundamental mode. Mathematical modeling is performed, which confirms the
efficiency of the method.
