Linear and nonlinear optical susceptibilities and the hyperpolarizability of borate LiBaB9O15 single-crystal: theory and experiment.
Ali H. Reshak,Xuean Chen,Sushil Auluck,Hussin Kamarudin,J. Chyský,A. Wojciechowski,I.V. Kityk +6 more
TL;DR: The nonlinear optical susceptibilities, namely, the second harmonic generation and the hyperpolarizability of the single-crystal borate LiBaB9O15 are calculated and evaluated at a static limit and at λ = 1064 nm, and the calculation shows there exists three second-order non linear optical susceptiblities tensors components.
