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 March newsletter is now available. In this issue we announce a web page dedicated to Lake Shore‘s range of cryogenic temperature sensors, reveal Laser Focus World‘s in-depth article on Fibercryst’s Taranis single crystal fibre laser technology, look at NoIR LaserShields‘ flip-frame protective eyewear, and cover CRAIC Technologies’ 508 PV microspectrophotometer add-on for microscopes, plus news of four events we are attending in April.

Fibercryst’s ultra-fast lasers and amplifiers utilise their revolutionary Taranis Single Crystal Fibre (SCF) modules to enable higher energy per pulse, higher average power, and easy to use flexibility between energy and repetition rate, and better beam qualities from small footprint devices.
In this month’s Laser Focus World magazine, an in-depth article about Fibercryst’s innovative Single Crystal Fiber amplification technology has been published. You can read Single crystal fibers amplify power in ultrashort-pulse lasers here.
Taranis technology is the heart of the Fibercyst FEMTO, a powerful industrial femtosecond pulse width laser for high quality micromachining, offering output powers up to 25 W for high throughput.
Typical applications include: cutting and drilling of hard materials, cold machining polymers or composites, and micromachining / structuring of surfaces, especially glass, ceramics and sapphire. A key feature of this laser is the ability to easily and quickly change the repetition rate to favour the average power or the energy per pulse.
The Taranis Amplifier System is a stand-alone add-on unit that allows a developer to increase the power and energy output of an existing laser installation.
The amplifier design also incorporates Fibercryst’s unique Taranis technology – a single crystal fibre amplifier ideal for short pulse amplification that delivers a high intensity, linearly polarised laser beam with superb quality and adjustable repetition rate.
The amplifier accepts a wide range of fibre-coupled or free propagation mode seed lasers, boosting them to a higher average power, higher peak power (up to 30 MW) and higher pulse energy. Output is to free space.
