![]() A635, Boke Mansion No. 9 Xiyuan Road Xihu District, Hangzhou 310030 China See us at LASER World of Photonics 2025 in Munich, June 24–27 (hall B1, booth 258)! | ![]() Periodically poled lithium niobate (PPLN) crystal is a type of nonlinear optical crystal with distinguished high conversion efficiencies and a wide transparency range of 0.4–5 μm. The 5% MgO doping in LiNbO3 improves the damage threshold of the PPLN to a significant extent and broadens its phase-matching bandwidth. MgO:PPLN crystals exhibit a unique quasi-phase-matching (QPM) phenomenon, which allows the utilization of a higher nonlinear coefficient than in the case of birefringent phase matching Shalom EO offers standard and off-the-shelf MgO:PPLN crystal and waveguides for SHG of 976 nm to 2100 nm and for various up-conversion and down-conversion applications including DFG, SFG, OPO, and OPA. Different dimensions, MgO concentrations, and AR coatings are available for selection. Product-specific web page |
