We report on the optical cooling of a 7.5% Y b : L i Y F 4 crystal down to 125 K in a multi-pass Herriott absorption cell, coupled via a single mode polarization maintaining optical fiber to the laser source. This configuration, never exploited befor

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

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

Laser cooling allows vibration-free cryocooling down to 100K and appears as a promising technology for future satellite missions. We evaluate the impact of a laser cooler onboard a microsatellite on size, weight and power at platform levels and compa

In the perspective of building a solid state cryocooler based on optical refrigeration, it is strategic to develop high purity crystals and to have a full understanding of the mechanisms that can reduce cooling efficiency. In this paper we highlight

In the last two decades, cryogenic temperatures have been reached in the field of the optical refrigeration in solids. These results have attracted a lot of interest to develop a solid-state cryocooler. A truly vibration-free device is appealing for
