一、前言采用加热金属产生蒸气的方法,就能得到各种金属蒸气激光器。其中,铜蒸气激光器因具有高增益、高输出功率和产生高重复脉冲振荡等特点而引人注目。但是,为了从金属铜得到激光器工作所需的蒸气压,必须把金属铜加热到1400～1500℃。二、复合蒸气的产生 1967年E. W. Dewing曾报导,铝和铁的三氯化物和钙、镁、锰、钴和铅的二氯化物之间生成气相复合体,例如,CaCl_2(固体)在650℃的温度下通常具有2×10~(-6)托的蒸气压,然而,在与AlCl_3蒸气共存的情况下,具有高达23托的蒸气压。一般认为这种现象是由于产生CaAl_2Cl_8型复合蒸气的缘故。另外,1969年H. A.фye等人用氯化钕(Nd
First, the introduction of the use of heating metal to produce steam, you can get a variety of metal vapor laser. Among them, the copper vapor laser due to high gain, high output power and produce high repetitive pulse oscillation and other features attract the attention. However, in order to obtain the vapor pressure required for laser operation from metallic copper, it is necessary to heat the metallic copper to 1,400-1,500 ° C. Compound Vapor Generation EW Dewing reported in 1967 that a gas phase complex was formed between aluminum and iron trichlorides and calcium, magnesium, manganese, cobalt and lead dichlorides, for example, CaCl 2 (solid) at 650 ° C Typically has a vapor pressure of 2x10-6 Torr, however, with a vapor pressure of up to 23 Torr in the presence of AlCl3 vapor. Generally believed that this phenomenon is due to produce CaAl_2Cl_8-type composite steam sake. In addition, H. A.фye et al 1969 used neodymium chloride (Nd
