Near-Infrared Scanning Cavity Ringdown for Optical Loss Characterization of Supermirrors
Gar-Wing Truong, Georg Winkler, Tobias Zederbauer +6
A cavity ringdown system for probing the spatial variation of optical loss across high-reflectivity mirrors is described. This system is employed to examine substrate-transferred c…
