Laser-cooled
WebCryogenic cooling may be achieved with a cryogen such as liquid nitrogen or helium, ideally circulating through channels in a cooling finger which is attached to the laser crystal. The cryogen may be taken from some supply, which is refilled from time to time, or recycled in a closed loop, containing e.g. a Stirling engine. WebOct 26, 2024 · There has been much debate, experimentation, and documentation on the subject of water cooled lasers with regards to the main cooling fluid and additive combinations. The theoretical, as well as practical, implementations and observations vary from person to person and source to source. There exists a majority, however, of novices …
