Holographic Bragg gratings: measurements and examination diffraction parameters
E. A. Tikhonov, A. K. Lyamets
Measurement and analysis of diffraction parameters of thick transmission holographic phase gratings recorded on PHC-488 photopolymer are presented. Precision determination of the s…
Determination of refractive index of various materials on Brewster angle
Eugene A. Tikhonov
Studied experimentally the origin of the non-zero reflection of p-polarized radiation (TM) of Brewster's angle. The results have shown the residual reflected light in the vicinity…
Measurement of radiation coherence by means of interference visibility in the reflected light
E. A. Tikhonov, A. K. Lyamets
Proposed, justified and tested measuring of beam spatial coherence, based on the detection of an interference visibility of the equal to intensity of beam replicas emerging under r…
Refractive index of nanoscale thickness films measured by Brewster refractometry
E. A. Tikhonov, A. K. Lyamets, Yu. V. Malyukin
It is shown that reflective laser refractometery at Brewster angle can be usefull for precision measurements of refractive indexes (RI) in the transparency band of various films of…
