Stabilized dye laser for crystal electromagnetic calorimeter monitoring

Abstract : An on-line active laser light output stabilization system is developed. The system compensates for slow variations of the laser light output caused by temperature drifts and by the aging of laser elements. The system is used for tracking PbWO4 crystal transmission losses caused by the radiation damage for the CMS ECAL prototype tests at CERN.
