Abstract

$K_{2}(NbO)_{2}Si_{4}O_{12}$ consisting of trans-connected $Nb(V)O_{6}$ octahedral chains is a novel nonlinear optical (NLO) material synthesized by Tournoux and coworkers. Our investigation of several inorganic materials containing trans-connected $d^0:MO_{6}$ octahedral chains has identified fresnoite $(Ba_{2}TiOSi_{2}O_{7})$ as another structure type for second order NLO response. Here we describe the synthesis of a new fresnoite, $Ba_{1.5}$ $VOSi_{2}O_{7}$, that shows efficient second harmonic generation of 1064 nm radiation, lending support to the idea that trans-connected $d^0:MO_{6}$ octahedra with alternating long and short M_O distances is indeed a crucial structural unit for generation of efficient second order NLO response.
