Ytterbium thin disk laser paves the way for sensitive detection of air pollutants
Optical parametric oscillator pump with ytterbium thin plate laser. Credit: APL Photonics (2024). DOI: 10.1063/5.0230388 Along with carbon dioxide, methane is the main cause of global warming. To accurately detect and monitor climate pollutants in the atmosphere, scientists at the Max Planck Institute for the Science of Light (MPL) have developed advanced laser technology. A high-power ytterbium thin disk laser…
