Failure statistics for diode laser array modules and replacement model in large-scale laser systems

This paper presents a methodology for synthesizing diode-laser array module failure statistics from the failure statistics of constituent diode laser arrays. In addition, a model is elucidated for analyzing replacement strategies of systems containing large numbers of diode laser array modules. Simulations reveal the dependence of synthesized module failure statistics and replacement characteristics on module size and failure statistics of the constituent diode laser arrays.
