研究分析了He-Ne激光管寿命过程中各种因素的变化,发现在现在达到的寿命范围内,气体成分和压力的变化是影响寿命的次要因素,而镜片(?)损则是寿命终了的第一位原因。 The changes of various factors in the life of He-Ne laser tube were analyzed. It was found that the variation of gas composition and pressure was the secondary factor affecting the life span in the range of life span, and the loss of lens (?) Was the end of life The first reason.
