| 发明名称 | No-vibration cryogenic cooling of reference cavities for high-precision metrology using optical refrigeration | ||
| 摘要 | Provided is a method and system for stabilizing a property of a first laser beam from a first laser in a vibration-free and cryogen free-manner. The method can include optically cooling a ytterbium-doped yttrium lithium fluoride (Yb:YLF) crystal using a second laser beam; coupling the crystal to a thermal coupling, wherein the thermal coupling is further coupled to a reference cavity to maintain a temperate of the reference cavity; directing a portion of the first laser beam through the reference cavity onto a photodetector to measure the property of the first laser beam; and stabilizing the first laser beam using a feedback control mechanism using the photodetector. | ||

| 主权项 | 1. A method for stabilizing a property of a first laser beam from a first laser in a vibration-free and cryogen free-manner, the method comprising: optically cooling a ytterbium-doped yttrium lithium fluoride (Yb:YLF) crystal using a second laser beam; coupling the crystal to a thermal link, wherein the thermal link is further coupled to a reference cavity to maintain a temperate of the reference cavity; directing a portion of the first laser beam through the reference cavity onto a photodetector to measure the property of the first laser beam; and stabilizing the first laser beam using a feedback control mechanism using the photodetector. | ||
