Dispersion measurements results of mirrors contamination in vacuum
The contamination of the mirrors used in vacuum at different laser facilities is one of the factors that lead to damage to the mirrors. To mitigate this risk, we propose a non-invasive method based on broadband source interferometry to investigate the contamination quantitatively. By monitoring the phase, group delay, and group delay dispersion of the mirrors, we were able to qualify the contamination as a function of coating design, deposition method, and contamination time in the vacuum chamber.
