Influence of cation substitution on optical constants of (Cu1-xAgx)7SiS5I mixed crystals

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2020
(Cu1–хAgx)7SiS5I mixed crystals were grown using the vertical zone crystalliza-tion method, they have been shown to crystallize in cubic structure (). The diffuse reflection spectra for the powders of (Cu1–хAgx)7SiS5I mixed crystals were measured at room

Power scaling of tunable, narrowband, non-resonant PPLN optical parametric oscillators

Journal of the European Optical Society-Rapid Publications
We review our recent achievements with narrowband, nanosecond, non-resonant optical parametric oscillators based on periodically-poled LiNbO3, which are pumped at 1064 nm and emit close to degeneracy in the near-IR part of the spectrum between 1860 and ...

IR Image Upconversion Under Dual-Wavelength Laser Illumination

IEEE Photonics Journal, 2016
We investigate the use of dual-wavelength laser illumination in a nonlinear infrared-to-visible image upconversion system. We show how a two-wavelength laser illumination can combine the enhanced upconversion field-of-view (FOV) characteristic of ...
