The July issue of Laser Focus World magazine uses a photo of a YLF:Yb crystal mounted between two top-adjustable Siskiyou IXF monolithic tip/tilt flexure mounts to illustrate their feature story on an all-solid-state optical cryocooler developed by the Los Alamos National Laboratory and the University of New Mexico.
Solid-state optical refrigeration uses anti-Stokes fluorescence to cool macroscopic objects to cryogenic temperatures without the annoying vibrations typically introduced by mechanical cryocooling systems.
The crystal was excited by a low power linearly-polarised continuous-wave fibre laser by IPG Photonics, while the temperature was monitored with a calibrated DT-670-SD silicon diode from Lake Shore Cryotronics.
Coupling the laser light to the crystal was achieved by using an astigmatic Herriott cell, with the optics held in vacuum compatible Siskiyou IXF flexure mounts… known for their excellent mechanical and thermal properties.
Researchers in the UK or Ireland wishing to replicate this experiment can contact us for research lasers from IPG Photonics, sensors and instrumentation from Lake Shore Cryotronics, and the full range of mounts and stages from Siskiyou. Elliot Scientific can also be approached to supply optics and custom machined parts as well.
The full paper describing the experiment can be read here on nature.com.
The Elliot Scientific September newsletter is now available. In this issue we introduce Fibercryst – the only manufacturer of short pulse lasers and amplifiers utilising the innovative Single Crystal Fibre technology, gain insight with the latest THz accessory for Probe Stations from Lake Shore Cryotronics, invite you to watch Seebeck measurements being conducted using a CryoLab from Kryoz, and inform you about the Elliot Scientific range of optics, waveplates, mirrors and filters.
