چکیده

We report laser-induced cooling with thulium-doped BaY2F8 single crystals grown using the Czochralski technique. The spectroscopic characterization of the crystals has been used to evaluate the laser cooling performance of the samples. Cooling by 3 degrees below ambient temperature is obtained in a single-pass geometry with 4.4 Watts of pump laser power at lambda = 1855 nm.

Observation of anti-stokes fluorescence cooling in thulium-doped glass

We report the first observation of anti-Stokes fluorescence cooling in a thulium-doped solid with pump excitation at 1.82 &mgr;m<lambda<1.97 &mgr;m. At a pump wavelength of 1.9 &mgr;m and incident average power of approximately 3 W, a Tm3+:ZBLANP ( ZrF4-BaF2-LaF3-AlF3-NaF-PbF2) sample cooled to -1.2 degrees C from room temperature for a single pass of the pump beam. This corresponds to an absor...

Efficient luminescence extraction strategies and anti-reflective coatings to enhance optical refrigeration of semiconductors

Laser refrigeration of solids has emerged as a viable solution for vibration-free and compact cooling that does not require any moving parts or cryogenic liquid. So far, rare-earth doped glasses are the only bulk materials that have provided efficient laser cooling based on the anti-Stokes process. These materials have low indices of refraction and are suitable for efficient luminescence extrac...

Comparison of ultraviolet upconversion luminescence between thin film and bulk of calcium fluoride co-doped with Yb3+/Tm3+ ions.

A calcium fluoride thin film co-doped with Yb3+/Tm3+ was deposited on Si substrates by the spin-coating method using trifluoroacetic acid as a fluorine source. The scanning electron microscopy (SEM) image of the sample showed that a thin film with some cracks was formed. After annealing, the cracks disappeared, and the film became thinner. The roughness of the thin film was about 150 nm, which ...

Enhanced Upconversion Luminescence in Yb3+/Tm3+-Codoped Fluoride Active Core/Active Shell/Inert Shell Nanoparticles through Directed Energy Migration

The luminescence efficiency of lanthanide-doped upconversion nanoparticles is of particular importance for their embodiment in biophotonic and photonic applications. Here, we show that the upconversion luminescence of typically used NaYF₄:Yb3+30%/Tm3+0.5% nanoparticles can be enhanced by ~240 times through a hierarchical active core/active shell/inert shell (NaYF₄:Yb3+30%/Tm3+0.5%)/NaYbF₄/NaYF₄...

Enhanced laser cooling of rare-earth-ion-doped nanocrystalline powders

The enhanced laser cooling performance of rare-earth-ion-doped nanocrystalline powders is predicted, compared to the bulk material, using Yb:Y2O3 as the model material. This is achieved by enhancing the off-resonance, phonon-assisted absorption, which is proportional to the three factors considered in this paper: the dopant concentration, the pumping field energy, and the excitation coefficient...
