For the first time, scientists have created laser-cooled neutral plasma. The temperatures reached are around 50 times colder than that of deep space, with the plasma reaching -273C. Normally we think ...

Laser cooling has emerged as a transformative methodology for controlling the motion of atoms and molecules, utilising the momentum of light to reduce thermal motion at ultra‐low temperatures. This ...

How can light be used to cool atoms and molecules? How can light be used to cool atoms and molecules? Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can ...

Laser cooling and optical refrigeration are advanced techniques that utilise the interaction of laser light with matter to remove thermal energy from solids. Based on the principles of anti-Stokes ...

A bit over 25 years ago ago, probably late 1991 or very early 1992, when I was a still a student at Williams, I saw a talk by Claude Cohen-Tannoudji, and was absolutely blown away. He explained the ...

Slow motion: artistic illustration showing snippets of motion of an antihydrogen atom in the ALPHA magnetic trap, before and after laser cooling. The grey tracks are before cooling and the blue tracks ...

When most people think about lasers, they usually imagine them generating heat and even setting something on fire. But, for a group of scientists in The University of New Mexico’s Department of ...

The advent of laser cooling revolutionized the field of atomic physics, transforming atomic clocks and GPS technology and laying the foundations for quantum computing with atoms and ions. In the first ...

Additive Manufacturing (AM) is booming. According to a recent report from Persistence Market Research, the sector is currently on pace to grow by more than 22% this year and is expected to double in ...

Laser cooling, in which carefully arranged laser beams can reduce the momentum of an atom to the point where the it can be individually caught by a magnetic field, is an important technology for ...

Scientists at CERN have used lasers to cool down antimatter for the first time. The milestone could help unlock some of the secrets of this weird substance, including why it didn’t annihilate the ...

How laser diodes have become the technology of choice in laser projection. Thermal challenges posed by laser diodes. Details on why is thermoelectric cooling the most effective thermal solution. Laser ...
