The Rahman-Nat diffraction on a thin laser-induced grating of the refractive index in semiconductors
Studied in this work is the Rahman-Nat diffraction on a thin grating of
 refractive index in semiconductor, which was created by an interference pattern of two
 coherent laser beams. Numeral calculations showed that the maximal diffraction
 efficiency for the Rahman-Nat diffr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Studied in this work is the Rahman-Nat diffraction on a thin grating of
refractive index in semiconductor, which was created by an interference pattern of two
coherent laser beams. Numeral calculations showed that the maximal diffraction
efficiency for the Rahman-Nat diffraction in the first order was 28.2 % for a purely phase
grating at its thickness z ~ 200, and 4.8 % for a purely amplitude grating. It was also
ascertained, that waves belonging to the nearby diffraction orders differ from each other
by π/2 in their phase.
