A computer may include a database and a power reducing routine. The database may be configured to store an input power level of an input laser beam transmitted onto and storing power within a gain module. The database may be further configured to store a discharge power level of at least partially discharged stored power discharged from the gain module through an output laser beam. The database may also be configured to store a power safety differential limit. The power reducing routine may include an algorithm. The algorithm may be configured to calculate a power differential by subtracting the discharge power level from the input power level, and to at least one of reduce power to and shut down the input laser beam if the calculated power differential exceeds the power safety differential limit.
