Incoherent one beam recording in LiNbO3
نویسندگان
چکیده
We find a way to record and retrieve images in a photorefractive LiNbO3 crystal using a single white light source instead of a coherent light source. According to the experimental results, we think this recording is not due to the recording of fanning gratings, but a variation of refractive index responding to the non-uniform illumination. We have also simulated the recording using the band transport model taking into account the photovoltaic effect. The simulation result agrees with the experimental results. 2007 Elsevier 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 کاملThe role of carrier mobility in holographic recording in LiNbO3
We investigate the role of carrier mobility in holographic recording in LiNbO3 crystals. Both normal holographic recording (single wavelength, single trap) and twocenter recording are considered, and the differences between the performances of the two methods are explained. We show that increasing mobility by using stoichiometric crystals or by doping with Mg does not improve sensitivity consid...
متن کاملHigh aspect ratio LiNbO3 photonic crystals Toward 3D LiNbO3 micro and nano structures
We report easy to implement techniques for the fabrication of high aspect ratio LiNbO3 photonic crystals. The methods rely on optical grade dicing followed by focused ion beam (FIB) milling. A 2D photonic crystal with an extinction ratio of -14dB is demonstrated. We show how the techniques can be combined for the development of 3D photonic crystals.

متن کاملFolded shift multiplexing.
Shift multiplexing is a holographic recording method that uses a spherical reference wave. We extend the principle to a thin slab of holographic material that acts as a waveguide. Total internal reflection folds the reference spherical beam in one dimension. We demonstrate that the shift selectivity with the folded spherical beam is independent of the slab thickness but depends instead on the n...

Combined high precision RBS/channeling, NRA/channeling and perturbed angular studies were used to characterize near-stoichiometric and congruent LiNbO3 single crystals. In congruent LiNbO3 two non-equivalent Li sites are distinguished whereas in near-stoichiometric LiNbO3 only one of them exists. A comparison of the experimental results with Monte Carlo simulations was performed to check the va...
