Abstract:

Constant-stress accelerated Life test is a rapid and effective method for obtaining the failure data and making life prediction of the electric component. This paper first applies this method for the He-Ne ring laser. A new prior distribution function based on the distribution of the life test data of the He-Ne ring laser is introduced. According to accelerated life equations, formulation of life prediction of the He-Ne ring laser is obtained and test data of the He-Ne ring laser are also analyzed.This method which was proved by experimentation not only precisely estimates the life of the He-Ne ring laser, but also considerablely shortens the test cyclebut.

Key words: accelerated life testing, prior distribution, He-Ne laser, ring laser
