Experimental investigation on the scintillation index of vortex beams propagating in simulated atmospheric turbulence
Experimental investigation scintillation index vortex beams propagating simulated atmospheric turbulence
2013/7/3
The scintillation index of vortex beam in simu-lated atmospheric turbulence is experimentally investigated.The fluctuation of the intensity can be effectively reduced by vortex beams. In particular, t...
Experimental investigation on partially coherent higher-order non-diffractive beams
physical optics higher-order non-diffractive Bessel beam axicon partially coherence
2013/7/3
We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axicon. The investigation results show that when the partially ...
Experimental Investigation of Temperature Effect on Refractive Index of Dye Laser Liquids
Temperature Effect Refractive Index Dye Laser Liquids
2010/4/13
In this work, refractive index of selected dye laser solutions were measured by fiber optic sensor. The fiber optic probe was dipped into the liquids and according to Fresnel's Reflection Law, refract...
