Second order optical nonlinearity of surface crystallized glass with lithium niobate

Significant second harmonic generation was observed for a surface crystallized but transparent glass of 35Li2O⋅30Nb2O5⋅35SiO2 (in mol %), for which the crystalline layer (about 0.35 μm in thickness) was composed of partially c-axis oriented and connected LiNbO3 fine grains. The effective second orde...

Description
Summary:Significant second harmonic generation was observed for a surface crystallized but transparent glass of 35Li2O⋅30Nb2O5⋅35SiO2 (in mol %), for which the crystalline layer (about 0.35 μm in thickness) was composed of partially c-axis oriented and connected LiNbO3 fine grains. The effective second order nonlinear optical susceptibility of the film deff reached ∼5.25 pm/V after adjusting the incident angle. The tensor components of the film were d33=6.9 pm/V and d31=d21=d24=d15=1/3d33=2.3 pm/V if the partially c-axis oriented thin film was described by a space group C∞V.
