氢与某些金属和合金之间相互作用的可逆性,在满足氢激射器的氢源供应、氢气流量调节以及保持真空度等方面,得到了十分有效的应用。此外,氢化物在减小激射器的体积、重量和功耗以及改进系统的可靠性等方面都有重要作用。可供振荡式小型化氢激射器运行七年的氢源,可以存储在50克LaNi_5或50克LaNi_(4.7)Al_(0.3)中。包括一个电控钯银合金稳流器在内,氢源所占的容积小于50毫升。为氢激射器配套的吸气剂——离子真空泵组合装置中,用锆石墨作吸气剂。工作经验表明,为确保激射器运行可靠,需要具备洁净的、可烘烤的真空系统。这种真空系统的设计要求是十分严格的。
The reversibility of the interaction between hydrogen and some metals and alloys has been proved to be very effective in meeting the hydrogen source supply of hydrogen lasers, regulating the flow of hydrogen and maintaining the degree of vacuum. In addition, hydrides play an important role in reducing the size, weight and power consumption of lasers and in improving the reliability of the system. Hydrogen sources that can be used for oscillating miniaturized hydrogen lasers for seven years can be stored in 50g of LaNi_5 or 50g of LaNi_ (4.7) Al_ (0.3). Including an electrically controlled palladium-silver alloy stabilizer, the hydrogen source accounts for less than 50 ml. Hydrogen lasers supporting the getter - ion vacuum pump combination device, with zirconium graphite as getter. Experience has shown that in order to ensure reliable operation of the lasers, a clean, toasted vacuum system is required. This vacuum system design requirements are very strict.
