摘要：

Ultra-small temperature variations measurements are usually not a trivial task. However, we propose an experimental setup which is relatively simple and can be achieved in a university teaching laboratory. The method used in this study combines a laser interferometer and a bimetal as a temperature sensor to accurately measure milliKelvin temperature variations. We used this setup to quantify the heating capability of low-power continuous laser beams.
