In order to find the theory model and lifetime test method of life estimate of He-Ne laser with circular cavity under specific conditions of use,it is assumed in this paper that the lifetime distribution of He-Ne laser with circular cavity work at high electric current obeys Weibull distribution,accelerating life test of the He-Ne laser carried on increasing electric current as acceleration stress.Least-square method is used to process the test data.The results shows that the assumption is correct and the characteristic life of He-Ne laser with circular cavity working at normal electric current can be calculated through that at high electric current,effectively reducing the time of the test.

Key words: He-Ne laser with circular cavity;high current stress;Weibull distribution;accelerated life test
