Hexagonally poled lithium niobate (HEXLN)

Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000
Summary form only given.The concept of quasi-phase matching (QPM) nonlinear optical processes by periodically inverting a material's nonlinear susceptibility (/spl chi//sub 2/) is a familiar one in 1-D: a well known example is periodically-poled lithium niobate LiNbO/sub 3/ (PPLN) which is commonly used for optical frequency conversion applications.

Control of Intrinsic Defects in Lithium Niobate Single Crystal for Optoelectronic Applications

Crystals, 2017
A single crystal of lithium niobate is an important optoelectronic material. It can be grown from direct melt only in a lithium deficient non-stoichiometric form as its stoichiometric composition exhibits incongruent melting.
