- Title
New milestone in laser cooling: research team succeeds in cooling silica glass by a record 67 K.
- Abstract
A research team from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and the University of New Mexico has achieved a new milestone in laser cooling by successfully cooling silica glass by a record 67 K. This cooling process, known as anti-Stokes fluorescence cooling, involves exciting a high purity material with laser light radiation, extracting energy from the material in the form of heat, and cooling it. This breakthrough has potential applications in the development of stable lasers, precision metrology, quantum experiments, materials analysis, medical diagnostics, and high-performance fiber lasers. The researchers believe that this achievement is not the maximum temperature reduction possible using laser light.
