Fluoindinate glass (FIG) is considered an ideal material for fiber laser devices and mid‐infrared bulk optics components owing to its ultra‐low phonon energy and broad transparency window. However, the heat generated by devices fabricated with FIG during their operation limits its application. Therefore, there is an urgent need to study its high‐temperature properties. In this study, the thermal properties,...
A method for measuring thickness of glass is proposed based on laser heterodyne measurement and Doppler measurement, the largest error of simulation results is 0.8%.
