We report the first experimental demonstration of stable, efficient, continuous-wave lasing of a femtosecond laser written, 1.3 µm channel waveguide laser in a Nd3+:BaY2F8 crystal without any parasitic lasing in the 900-1500 nm spectral region.

For optical refrigeration to become a viable option for cryogenics, it is fundamental to improve the overall cooling power of an optical cryocooler. In this paper, we propose a design that might be able to cool down a thermal load to temperatures low

Publikováno v: 2020 IEEE International Workshop on Metrology for Agriculture and Forestry (MetroAgriFor).

At present, technological support may specifically contribute to develop and to improve the aquaculture production, and in particular the fish production in offshore pens. Estimating live-fish biomass is extremely relevant to optimize the whole growt

In this work, we present the cooling efficiency of a LiYF4 (lithium yttrium fluoride,YLF) sample co-doped with 10at.% ytterbium (Yb3+) and 0.0040at.% thulium (Tm3+). For the first time at room temperature, the cooling efficiency of a sample overcomes

Eu3+-Doped CaMoO4 single-crystal fibers with concentrations from 0.01 to 1 at% have been grown by the micro-pulling-down method in an air atmosphere. The origin of the coloration of the crystals can be attributed to the charge compensations. In the a
