Comparison of Glass Material and Laser Excitation Regime for Upconversion‐Based 3D Volumetric Display

Advanced Photonics Research, EarlyView.
This study explores scalable glass matrices for two‐step, two‐frequency (TSTF) upconversion‐based 3D volumetric displays. While Er3+‐doped TeO2–ZnO–Na2O (TZN) and BaO–Ga2O3–GeO2 (BGG) glasses show weaker TSTF upconversion than reference ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) glass under continuous‐wave lasers, TZN surpasses ZBLAN under pulsed laser excitation

Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

Advanced Photonics Research, EarlyView.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations
