Efficient generation of >2 W of green light by single pass frequency doubling in PPMgLN
, 2007 We report 32% efficient frequency doubling of single frequency 1029 nm light to green light at 514.5 nm using a single pass configuration. A congruent composition, periodically poled magnesium doped lithium niobate (PPMgLN) crystal of 50 mm length was ...

Integrated lithium niobate photonics
Nanophotonics, 2020 Abstract Lithium niobate (LiNbO3) on insulator (LNOI) is a promising material platform for integrated photonics due to single crystal LiNbO3 film’s wide transparent window, high refractive index, and high second-order nonlinearity. Based on LNOI, the fast-developing ridge-waveguide fabrication techniques enabled various structures ...

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.
