Description

We compute the low-frequency tail of the power spectral density of thermal noise in the case of an optical Fabry–Perot resonant cavity operating with Laguerre–Gauss modes of orders higher than (0, 0). We show a significant reduction of the thermal noise as the order of the mode increases. We discuss the diffraction losses.
