Cryogenically-Cooled Lasers (Jacob I Mackenzie, Nikolay Ter-Gabrielyan, Yung Fu Chen)

Energy scaling with high average power has become increasingly important in pursuing extreme-light conditions. Technological advances in cooling gain media to cryogenic temperatures are enabling next generation laser systems yielding a wide variety of scientific and industrial applications. Extended operating regimes, using new and traditional gain media, are being explored for tailored light-matter interactions with ever greater efficacy. This topical issue is dedicated to developments at the frontiers of cryogenically-cooled laser technology, ranging from the continuous-wave to the ultrafast femtosecond domain, including their applications across all the physical sciences.
