当前判断激光管的工作寿命要靠实际点燃来实验,这对管子的检验、改革、研究极端不利。因此,探索一种较可靠的快速推算其寿命的方法,是极待解决的课题。激光管的失效原因是多方面的,但从国内当前的生产水平来看,管内杂气,腔变形、慢漏、镜片污染等造成的管子失效因素均 The current judgment of the working life of the laser tube depends on the actual ignition to experiment, which is extremely unfavorable to the inspection, reform and research of the tube. Therefore, to explore a more reliable and rapid method to calculate the life expectancy is a subject to be solved. Laser tube failure is due to many reasons, but from the current domestic production level, the tube miscellaneous gas, cavity deformation, slow leakage, lens pollution caused by the tube failure factors are
