Reorientation with a micron lattice constant in unsteady optical four-wave mixing in a nematic liquid crystal
Zel'dovich B. Ya., Pilipetskii N. F., Sukhov A. V.
A four-wave mixing of a ruby laser beam (r~ 10~3 s) is used to excite and then to detect reorientation space lattices of a nematic liquid crystal with an extremely small lattice constant Λ, reaching values as small as A/2rr = 2.7 X 10~5 cm.
