Calculating properties of non-collinear phase matching in two different polarization for KDP crystal

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Crystal defects and electro-optical properties of D-KDP

2014 This article presents a qualitative approach of the relationship between the occurrence of crystal defects and the disturbances of the induced birefringence which appear during the operation of (001) D-KDP solid-state light-valves. The crystal defects are ascribed to growth or seed effects, and both contributions to the above disturbances are discussed. On this basis, conclusions are drawn...

Collinear phase matching for second harmonic generation using conoscopic interferometry

Polarization-entangled photon-pair source obtained via type-II non-collinear SPDC process with PPKTP crystal.

We demonstrate a polarization-entangled photon-pair source obtained via a type-II non-collinear quasi-phase-matched spontaneous parametric down-conversion process with a 10-mm periodically poled KTiOPO4 crystal, which is as stable and wavelength-tunable as the well-known Sagnac configuration scheme. A brightness of 4.2 kHz/mW is detected and a concurrence of 0.975 is estimated using quantum sta...

A Polarization Independent Microlens using Two Blue-Phase Liquid Crystal Layers with Different Kerr Constant

We propose a new microlens device structure using two polymerstabilized blue phase liquid crystal layers whose Kerr constant is largely different. Such a polarization independent microlens has a simple structure and desired parabolic phase profile. Its applications for 2D/3D switchable displays and other photonic devices are emphasized.
