【摘要】 提供了激光质量的碱卤色心晶体加质着色用热管仪的设计要点和运行结果。其特点是:1)设计了特殊的‘灯芯’结构,使碱金属的蒸发冷凝区和加色区分开,从而色心的类型、浓度可以精密地加以控制;2)经过予抛光的晶体,经过加色和随后的聚集等过程,可直接装入激光器;3)一次装炉可供多次着色,并能连续操作,可方便地,经济地用来生产激光质量的着色晶体;4)利用DWT-702精密温度控制仪对炉温实现了精密调节,可较为细致地研究加色温度对色心类型、浓度及均匀性的影响。更多还原

【Abstract】 A precise heat-pipe apparatus for the additive coloration or laser-quality alkali halide crystals is described. It has the following features: (1) with a specially desinged "wick" construction the region of metal vapor can be separated from the region of additive coloration and the F-center densities are very precisely and simply controlled. (2) Prepolished crystals are ready for direct installation in the laser. (3)An air lock allows the same charge of alkali metal to be used many times. (4) By using the DWT-702 precise automatic temperature control apparatus, the system can attentively record the effect of temperature in the additive coloration process.更多还原
