提出了金属蒸气激光器中金属原子在激光器隔离头中运动的理论模式──无规行走模式．从实验上验证了该模式．在此理论模式的基础上．设计出一种新的抗金属蒸气污染的隔离头．其原理是．在金属蒸气原子无规行走过程中．用多片高凝结系数的金属片来吸附碰撞在它上面的金属蒸气原子．从而实现对窗口的保护作用．还用ＭｏｎｔｅＣａｎｌｏ数值模拟方法．模拟了金属原子的运动，显示了新型隔离头的抗污作用．它的抗污能力比普通的隔离头有明显的提高．
A theoretical model of metal atoms in a metal vapor laser moving in a laser head is proposed, which is a random walk mode. This model is verified experimentally. On the basis of this theoretical model. Design a new anti-metal vapor contamination isolation head. The principle is. During the random walking of metal vapor atoms. Multiple pieces of metal with high Coefficient of Condensation are used to adsorb the metal vapor atoms impinging on it. In order to achieve the protection of the window. Also used MonteCanlo numerical simulation method. Simulating the movement of metal atoms shows the anti-fouling effect of the new spacer head. Its anti-fouling ability is obviously improved compared with the ordinary isolation head.
