Critical Power Density: A Metric To Compare the Excitation Power Density Dependence of Photon Upconversion in Different Inorganic Host Materials.

In photon upconversion (UC) based on triplet-triplet annihilation, the upconversion photoluminescent quantum yield (UC-PLQY) depends on the excitation power density in a way that can be described by a single figure of merit. This figure of merit, the threshold value, allows the excitation power density required for efficient UC-PLQY to be compared between different triplet-triplet annihilation systems. Here, we investigate the excitation power density dependence of two-photon UC processes in a series of four lanthanide-doped inorganic host materials (oxides, fluorides, and chlorides) all doped with 18 mol % Yb sensitizer ions and 2 mol % Er activator ions.

Highly Efficient LaO:Yb,Tm Single-Band NIR-to-NIR Upconverting Microcrystals for Anti-Counterfeiting Applications.

Efficient single-band NIR-to-NIR upconversion (UC) emission is strongly desired for many applications such as fluorescent markers, plastic recycling, and biological imaging.

Under 980 nm laser excitation, LYT exhibits a NIR UC emission at ∼795 nm (Tm: H → H) and blue UC emission at ∼476 nm; the NIR UC emission is dominant, with the intensity ratio of the NIR to blue I/ I > 100.

Maintaining broadband gain in a Nd/Ybco-doped silica fiber amplifier via dual-laser pumping.

We report a 30 cm long Nd/Yb co-doped silica glass fiber amplifier with well-maintained broadband gain through simultaneous dual-laser pumping at 808 and 975 nm. By controlling the ratio of the pump power at 975 (P) and 808 nm (P), the emission band of Yb/Nd and the energy transfer efficiency of Nd→Yb can be well controlled; thus, a tunable broadband and flat gain in the range of 1036-1080 nm are obtained. The theoretical calculation of the energy transfer efficiency of Nd→Yb with dual-laser pumping of 808 and 975 nm explains well the mechanism of broadband and flat gain formation in the Nd/Yb co-doped fiber.

Manipulating refractive index, homogeneity and spectroscopy of Yb-doped silica-core glass towards high-power large mode area photonic crystal fiber lasers.

Output power scaling of single mode large mode area (LMA) photonic crystal fiber (PCF) amplifiers urgently requires the low refractive index of Yb-doped silica glasses whilst maintaining high optical homogeneity.

By controlling the doping combinations of Al/F/P in Yb-doped silica glass,it not only ensures low refractive index (RI) but also maintains the excellent optical homogeneity and spectroscopic properties of Yb.

Microsecond molecular dynamics simulations provide insight into the ATP-competitive inhibitor-induced allosteric protection of Akt kinase phosphorylation.

Akt is a serine/threonine protein kinase, a critical mediator of growth factor-induced survival in key cellular pathways. Allosteric signaling between protein intramolecular domains requires long-range communication mediated by hotspot residues, often triggered by ligand binding. Here, based on extensive 3 μs explicit solvent molecular dynamics (MD) simulations of Akt1 kinase domain in the unbound (apo) and ATP-competitive inhibitor, GDC-0068-bound states, we propose a molecular mechanism for allosteric regulation of Akt1 kinase phosphorylation by GDC-0068 binding to the ATP-binding site.
