Optothermal stability describes the rate at which an optical element distorts due to a changing thermal environment. A changing thermal environment can cause an optic to bend due to either 1) changing thermal gradients on the optic and a non-zero coefficient of thermal expansion, or 2) coefficient of thermal expansion gradients in an optic and an average temperature change. Therefore, optothermal stability is an issue for optics that are present in a changing thermal envi… WebDec 1, 2024 · When using the optical actuation and detection method, the optothermal effect induced heat dissipation on graphene. When optical power rise, the resonance frequency blueshifts in an exponential relationship, whereas amplitude rises in a linear relationship. josh wright instagram
