Neutron optical beam splitter from holographically structured nanoparticle-polymer composites

open access: yes, 2010
We report a breakthrough in the search for versatile diffractive elements for cold neutrons. Nanoparticles are spatially arranged by holographical means in a photopolymer. These grating structures show remarkably efficient diffraction of cold neutrons up

Holographic interferometry with an injection seeded Nd:YAG laser and two reference beams [PDF]

open access: yes
The performance of twin injection seeded Nd:YAG lasers is compared with the performance of an argon-ion laser for recording dual-reference-beam holograms in AGFA 8E56 emulsion.
