Compensation for thermal effects in mirrors of Gravitational Wave Interferometers [PDF]
, 2001 In this paper we study several means of compensating for thermal lensing which, otherwise, should be a source of concern for future upgrades of interferometric detectors of gravitational waves. The methods we develop are based on the principle of heating

Simulation and compensation of thermal lensing in optical systems
Optics Express, 2022 High-power optical systems are used in a number of industrial applications. One difficulty in designing such systems is that the beam itself is a significant source of heat, which changes the optical properties of the system. To reduce this effect, we propose a new thermal lensing compensation technique based on a detailed analysis of the optical ...

Thermal noises and noise compensation in high-reflection multilayer coating [PDF]
, 2008 Thermal fluctuations of different origin in the substrate and in the coating of optical mirrors produce phase noise in the reflected wave. This noise determines the ultimate stabilization capability of high-Q cavities used as a reference system.

Handling Ambient Temperature Changes in Correlative Thermal Error Compensation
Journal of Machine Engineering, 2023 Thermal errors are one of the lead causes for positioning inaccuracies in modern machine tools. These errors are caused by various internal and external heat sources and sinks which shape the machine tool’s temperature field and thus its deformation ...
