Near-normal-incidence extreme-ultraviolet efficiency of a flat crystalline anisotropically etched blazed grating

Applied Optics, 45(8), 1676.

By: M. Kowalski*, R. Heilmann*, M. Schattenburg*, C. Chang*, F. Berendse* & W. Hunter*

TL;DR: The measured efficiencies are high for uncoated gratings and agree well with a calculated model derived from a reasonable estimate of the groove profile, which presents opportunities to instrument designs for high-resolution EUV spectroscopy in astrophysics where high efficiency in high orders is desirable.

Nanometer-level repeatable metrology using the Nanoruler

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures, 21(6), 3097.

By: P. Konkola*, C. Chen*, R. Heilmann*, C. Joo*, J. Montoya*, C. Chang*, M. Schattenburg*

TL;DR: The Nanonruler’s metrology system that is based on digital frequency synthesizers, acousto-optics, and heterodyne phase sensing is presented, used to assess the fringe-to-substrate placement stability and the accuracy of the feedback signals. (via Semantic Scholar)
