The following presents a succinct summary of one or more embodiments in order to provide an introductory understanding of the presently disclosed subject mailer. This summary is not an extensive overview of all contemplated embodiments and is not intended to single out any elements as being key or critical. Nor is it intended to delineate the full scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a streamlined Form as a prelude to the more detailed description that is presented later.According to one aspect of an embodiment, there is disclosed an automated maintenance system capable of monitoring performance of a laser system and requesting automated interventions when certain conditions are met. The interventions are referred to as containment actions or simply containments which are actions addressed to restoring within-specification operation. According to another aspect of an embodiment the containments are ranked in terms of invasiveness with less invasive containments being tried first and more invasive containments being performed only if the less invasive containments fail to restore normal operation.According to another aspect of an embodiment there is disclosed a method of maintaining a laser system, the method comprising using a classifier to determine whether a negative laser condition exists that may be corrected by an automated containment action, selecting as a first automated containment action, a least invasive automated containment action from a group of automated containment actions, performing the first automated containment action, using the classifier to determine whether the negative laser condition has been corrected by performance of the first automated containment action, if the classifier determines that the first automated containment action has not corrected the negative laser condition, then selecting as a next automated containment action a next least invasive containment action from the group of automated containment actions, and performing the next automated containment action.The group of automated containment actions may comprise N automated containment actions ranked according to invasiveness and the method may additionally comprise sequentially performing ones of the N automated containment actions until either the classifier determines that one of the N automated containment actions has corrected the negative laser condition or that none of the N automated containment actions has corrected the negative laser condition.According to another aspect of an embodiment, there is disclosed a method of maintaining a laser system, the method comprising training a first classifier using a first data type, using the first classifier to classify first data of the first data type, using the first data to train a second classifier to classify second data of a second data type, using the second classifier to classify the second data and to determine whether to perform an automated containment action, selecting an automated containment action to be performed if the second classifier determines to perform an automated containment action, and performing the automated containment action.The first data type may comprise data obtained from a gain scan performed by increasing a magnitude of a voltage applied to electrodes in a discharge chamber of the laser system and determining the laser output energy as a function of the magnitude of the voltage. The first data type may comprise data obtained from a timing scan performed by sequentially increasing a time gap between applying a master oscillator trigger voltage to a master oscillator chamber of the laser system and applying a power amplifier trigger voltage to a power amplifier chamber of the laser system to determine variation of an operational parameter as a function of the duration of the time gap. The second data type may comprise burst statistic data. Selecting an automated containment action may c
