Coherent and incoherent beam combination using thick holographic substrates
نویسندگان
چکیده
We present a mathematical model of coherent and incoherent beam combination in a thick hologram. We also derive the formulae relating the read and write angles to the read and write wavelengths for the combiner. Furthermore, we present a new technique for determining the M#, and establish that the M# required for a coherent combiner is substantially less than that needed for an incoherent one. 2003 Elsevier Science B.V.

Investigation of Coherent and Incoherent Laser Beams Propagation Through Turbulent Atmosphere
In this paper propagation of combined laser beam through atmosphere is investigated. Laser beam is combined via lens array arrangement. Turbulence is considered as an affecting factor of atmosphere and its effects on transverse coherence length (Fried parameter), peak intensity, propagation efficiency, and spot size of the laser beam is investigated. Coherent and incoherent combined beam are co...
متن کاملIncoherent dynamics in neutron-matter interaction
Coherent and incoherent neutron-matter interaction is studied inside a recently introduced approach to subdynamics of a macrosystem. The equation describing the interaction is of the Lindblad type and using the Fermi pseudopotential we show that the commutator term is an optical potential leading to well-known relations in neutron optics. The other terms, usually ignored in optical descriptions...
متن کاملDemonstration of a multiwave coherent holographic beam combiner in a polymeric substrate.
We demonstrate an efficient coherent holographic beam combiner (CHBC) that uses angle multiplexing of gratings in a thick polymeric substrate. Our experimental results compare well with the theoretical model based on the coupled-wave theory of multiwave mixing in a passive medium. A CHBC of this type may prove useful in producing a high-power laser by combining amplified beams produced by split...
متن کاملA STUDY OF GAMMA RAY EXPOSURE BUILDUP FACTORS IN STRATIFIED SHIELDS FOR POINT ISOTROPIC SOURCES, INCLUDING THE EFFECTS OF INCOHERENT AND COHERENT SCATTERING
The effects of including incoherent (bound-electron) and coherent (Rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (E?) range of 40 keV to 3 MeV. Incoherent scattering decreases the values of these factors in both layers up to E? ~ 200 keV and the effect i...
متن کاملSynthetic Aperture Digital Holography
Synthetic aperture is a well-known super-resolution technique which extends the resolution capabilities of an imaging system beyond the theoretical Rayleigh limit dictated by the system's actual aperture. Using this technique, several patterns acquired by an aperture-limited system, from various locations, are tiled together to one large pattern which could be captured only by a virtual system ...
