低温冷却激射器为测量频率偏移和存储壁涂敷材料的弛豫特性创造了有利条件。这种涂敷材料是从常态变为气态物质而被冻结在存储壁上的。我们对FEP—120聚四氟乙烯在77K至48K之间的原始测试结果作了报道,并把这些测量结果和法国de Saintfuscien在372K至77K之间的测试数据进行了比较。对激射器的某些设计性能作了说明。低溫激射器的氢分离器,完全密封在真空环境中,其温度77k。本文还介绍了在真空中工作的分离器和其它一些装置。这些装置已在常温激射器中被采用并进行了测试。它们既适合于太空环境又适合于在地面使用。
Cryogenic cooling lasers create favorable conditions for measuring frequency shift and relaxation properties of the deposited wall material. This coating material is frozen on the storage wall from normal to gaseous. We report on the original test results of FEP-120 PTFE between 77K and 48K and compare these measurements with the test data of the French de Saint-Michel at 372K to 77K. Some design features of the lasers are described. Hydrogen separators for cryogenic lasers are completely sealed in a vacuum environment at a temperature of 77k. This article also describes separators and other devices that work in vacuum. These devices have been used in room temperature lasers and tested. They are both suitable for space environment and suitable for use on the ground.
