Description
With ground-based, laser interferometric gravitational wave detectors in mind, laser-induced thermal effects in the beam splitter of a Michelson type interferometer are discussed. Thermal lensing effect on beam splitter arising from the non-spatial heat distribution has been discussed. A finite element model has been built to compute the temperature profile in the beam splitter. The optical phase shift resulting from the temperature dependence of the refractive index has been analyzed.
