Highly-dispersive mirrors reach new levels of dispersion

Abstract

© 2015 Optical Society of America. A highly-dispersive mirror with the unprecedented group delay dispersion of -10000 fs 2 in the wavelength range of 1025-1035 nm is reported. Reproducible production of a coating with such a high dispersion was possible due to the recently developed robust synthesis technique. Successful employment of the new highly-dispersive mirror in an oscillator is demonstrated.
