27 February 2007 Lifetime prediction of diode lasers with different ageing behavior

Abstract
Regression models are developed for lifetime prediction of diode lasers with increasing or decreasing operating current in the gradual degradation stage of their lifetime. Programmable expressions for laser lifetime extrapolation are presented. Analytical results are explicated by case examples based on measured data from reliability tests of commercially available 10mW and 650nm wavelength InGaAlP lasers conducted under accelerated ageing conditions.
