On the development path to pump modules for actual power plants significant progress regarding multiple performance parameters as well as the overall cost of the modules is required. In this paper, we focus on the reliability of laser diodes and present a multiphysics model to predict the threshold of catastrophic optical damage (COD).enSemiconductor lasersPredictive modelsLaser modesOptical pumpingDiode lasersReliabilityLaser fusionPump lasersPower generationPhotonicshigh-power laser diodesmultiphysics modelingcatastrophic optical damageinertial fusion energyconference paper
