Optics and optical instruments. Lasers and laser-related equipment. Lifetime of lasers seo-ignore1 Scope This International Standard covers terms and definitions as well as test methods and evaluation procedures to characterize, estimate and predict the longterm behaviour of various types of lasers. This International Standard defines terms for the lifetime of lasers and specifies test procedures and fundamental aspects for the determination of lifetime. It applies for all types of lasers for which lifetime is a critical issue, including diode
