Abstract
The knowledge of optical and thermal properties of materials at high temperatures is of crucial importance in the field of high power laser/material interactions. We report in this contribution on the development of a spectroscopic ellipsometry system dedicated to the measurement of optical properties of solid materials from the ambient to high temperatures (<1000 K). The experimental setup is based on a fiber-coupled high power laser diodes system operating at 800 nm used as remote heating, a supercontinuum source as probing beam, a fiber-optic spectrometer to measure reflected light and optical pyrometers for temperature monitoring.
