Transforms in Optics : The Legacy of P . - M . Duffieux

Simulation of an Airy Beam with Optical Vortex under Fractional Fourier Transforms

First, this study obtained the fields of an Airy beam (AiB) with optical vortex (OV) for a Fourier transform (FT) system and a fractional Fourier transform (fractional FT) system; thereafter, their intensity and phase patterns were simulated numerically. The splitting on each line of the phase pattern indicates the position of an OV. The results show that the OV position will change when the po...

The legacy of Islamic world in modern medicine and science

The legacy of the Islamic world in medicine and natural science is the legacy of Greece, increased by many additions, mostly practical. Rhazes, the Iranian, was a talented clinical observer, but not a Harvey. Abd al-Latif, the Arab, was a diligent seeker in anatomy, but in no way to be compared to Vesalius. The Muslims possessed excellent translations of the works of the Hippocratic Corpus and ...

The Fekete-Szego Coefficient Functional for Transforms of Analytic Functions

Investigation of Effective Parameters on Pulsed Nd:YAG Passive Q-Switched Laser

In this paper, we report the experimental results of a pulsed flash lamped Nd:YAG laser at wavelength of 1064 nm and Qswitched by Cr4+:YAG solid state saturable absorber. We have obtained the output energy (E) and pulse-width ( p τ ) of this laser for various initial transmissions of this saturable absorber. Furthermore, the effect of reflectivity of the output coupler (R), diameter of the rod ...
