- Abstract: Intracavity squeezing is a promising technique that may improve the
sensitivity of gravitational wave detectors and cool optomechanical oscillators
to the ground state. However, the photothermal effect may modify the occurrence
of optomechanical coupling due to the presence of a nonlinear optical crystal
in an optical cavity. We propose a novel method to predict the influence of the
photothermal effect by measuring the susceptibility of the optomechanical
oscillator and identifying the net optical spring constant and photothermal
absorption rate. Using this method, we succeeded in precisely estimating
parameters related to even minor photothermal effects, which could not be
measured using a previously developed method.
