Conversion of broadband IR-radiation in crystals of lithium niobate of stoichiometric and congruent compositions
Engineering Education # 07, July 2012
DOI: 10.7463/0712.0431642
The authors investigated conversion of broadband infrared radiation in lithium niobate crystal of stoichiometry and congruent compositions at noncritical 90°- phase-matching condition for vector interactions of light waves. It was shown that conversion efficiency, spectral width and position of the spectrum maximum of the converted broadband radiation depend on the ratio R = Li /Nb in the crystal of lithium niobate. The authors proposed to use the dependence of spectrum maximum of the converted broadband radiation on the composition and structure of crystal as the exact experimental criterion to determine the ratio R = Li/Nb in the crystal of lithium niobate.
