Diffraction Gratings for Neutrons from Polymers and Holographic Polymer-Dispersed Liquid Crystals

We discuss the applicability of holographically recorded gratings in photopolymers and holographic polymer-dispersed liquid crystals as neutron optical elements. An experimental investigation of their properties for light and neutrons with different grating spacings and grating thicknesses is performed. The angular dependencies of the diffraction efficiencies for those gratings are interpreted ...

A novel tunable diode laser using volume holographic gratings

We have developed a self-aligned external cavity laser with a non-dispersive volume holographic grating (VHG) as the output coupler. The resulting external cavity is tunable by rotating the VHG. We have demonstrated tunable single mode longitudinal operation at 405 nm and 785 nm wavelength. The passive alignment of the novel tunable laser is the main driver for achieving low cost manufacturing....

A simple method for Bragg diffraction in volume holographic gratings

We discuss a simple beam interference approximation method for deriving the angular selectivity of diffraction in weakly modulated volume holographic gratings. The results obtained using the multiple beam interference model agree qualitatively with the results obtained from a physical optics treatment of the coupled-wave theory for volume holographic gratings. © 2009 American Association of Phy...
