Simultaneous SHG of orthogonally polarized fundamentals in single QPM crystals

Johnston, Benjamin F; Saltiel, Solomon M; Withford, Michael; Kivshar, Yuri


Fabrication of quasi-phase-matching (QPM) gratings suitable for cascading of two second-order parametric nonlinear processes in a single lithium niobate crystal is being undertaken using a new technique - electric field poling assisted by laser micro-machined topographical electrodes. To date, single period poled gratings with 45.75, and 45.8 μm periods have been fabricated in order to demonstrate second harmonic generation of 1064nm laser light with 1st order type-I and 7th order type-0 QPM...[Show more]
