Solid-state Laser Cooling
Yang Ding, Shenghao Zhang, Alexander R. Albrecht +8
Since the first proof-of-concept demonstrations of photoluminescence-based optical refrigeration, solid-state laser cooling has developed into a credible competitor to conventional…
Thermal imaging by utilization of CsPbBr3 quantum dot photoluminescence
Alireza Jalouli, Nathan Giannini-Hutchin, Alexander R. Albrecht
The temperature-dependent photoluminescence of perovskite quantum dots (CsPbBr3) in the visible band, is analyzed to evaluate their suitability for use in thermometry. A differenti…
Laser Cooling of a Yb Doped Silica Fiber by 18 Kelvin From Room Temperature
Brian Topper, Mostafa Peysokhan, Alexander R. Albrecht +10
A ytterbium doped silica optical fiber has been cooled by 18.4K below ambient temperature by pumping with 20W of 1035nm light in vacuum. In air, cooling by 3.6K below ambient was o…
Probing the ultrafast gain and refractive index dynamics of a VECSEL
Christian Kriso, Tim Bergmeier, Nathan Giannini +9
Typically, strong gain saturation and gain dynamics play a crucial role in semiconductor laser mode-locking. While there have been several investigations of the ultrafast gain dyna…
Laser-induced anti-Stokes fluorescence cooling of ytterbium-doped silica glass by more than 6 Kelvin
Mostafa Peysokhan, Saeid Rostami, Esmaeil Mobini +12
Laser cooling of a solid is achieved when a coherent laser illuminates the material, and the heat is extracted by resulting anti-Stokes fluorescence. Over the past year, net solid-…
Laser Cooling of Silica Glass
Esmaeil Mobini, Saeid Rostami, Mostafa Peysokhan +11
Laser cooling of a solid is achieved when a coherent laser illuminates the material in the red tail of its absorption spectrum, and the heat is carried out by anti-Stokes fluoresce…
