Good news!
"... We've previously seen laser cooling methods being used to chill antimatter, aid in biological research, and to study quantum phenomena. Together with researchers at the University of New Mexico, this team is working on a completely new technology called laser-based photonic cooling. ...
Data center chips are typically cooled using cold water that flows through microscopic channels in copper plates mounted on top of the processors. The scientists are taking a totally different approach. They intend to create a photonic cold plate with tiny features, about a thousand times smaller than the width of a human hair, to channel cooling lasers to target hotspots. ..."
"... Because laser light will heat up impurities, erasing any cooling effect, the cold plate needs to have extremely pure, thin layers of crystalline gallium arsenide, also known as epitaxial layers, to work. ..."
"... development of a photonic cold plate designed to replace or complement traditional air- and water-based cooling systems. By harnessing laser light to target and cool localized hot spots on chips – such as GPUs – the technology aims to reduce power consumption, improve efficiency, and enable energy recovery paradigms not possible with conventional methods. ...
“A successful project will not only address the immediate need for energy savings but also pave the way for processors to operate at performance levels that were previously thought impossible,” ...
Under the CRADA [Cooperative Research and Development Agreement], Maxwell Labs will provide the technical designs, Sandia Labs will fabricate highly pure gallium arsenide-based devices using its expertise in molecular beam epitaxy, and UNM will evaluate the thermal performance of the resulting systems. ..."
