Modelling adapted to manufacturing aspects of holographic grating structures [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 The diffraction efficiencies of modified sinusoidal and blazed gratings are investigated in the high spatial frequency regime by rigorous numerical methods and are compared to experimentally manufactured gratings. The introduced modifications take actual

Directional enhancement of selected high-order-harmonics from intense laser irradiated blazed grating targets [PDF]
, 2017 Relativistically intense laser solid target interaction has been proved to be a promising way to generate high-order harmonics, which can be used to diagnose ultrafast phenomena. However, their emission direction and spectra still lack tunability.
