Interconversion of Optical to Terahertz Pulses in Nonlinear Beta Barium Borate Crystal

Advanced Physics Research, EarlyView.
ABSTRACT Low‐temperature β‐phase barium borate (β‐BBO) is an important nonlinear crystal, widely utilized for optical second‐harmonic (SH) generation. Recent re‐measurements of refractive indices in the terahertz (THz) range reveal that β‐BBO is a positive uniaxial crystal.

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.

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.
