Laser maintenance apparatus and method

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 a selected automated containment action to be performed if the second classifier determines to perform the automated containment action;
• and
• performing the selected automated containment action.

A method of maintaining a laser system, the method comprising:

• classifying a first data type using a first classifier to obtain first type classification data;
• using the first type classification data to train a second classifier to classify a second data type;
• using the second classifier to determine whether an automated containment action should be performed on the basis of the second classifier classifying the second data type;
• selecting a selected automated containment action to be performed if the second classifier determines to perform the automated containment action;
• and
• performing the selected automated containment action.

An apparatus for maintaining a laser system, the apparatus comprising:

• a classifier adapted to determine whether a negative laser condition exists that may be corrected by an automated containment action;
• an automated containment action selection unit adapted to select, in response to the classifier determining that the negative laser condition exists, as a first automated containment action a least invasive automated containment action from a plurality of automated containment actions;
• and
• a first automated containment action performance unit adapted to cause the laser system to perform the first automated containment action;
• wherein the classifier is further adapted to determine whether the negative laser condition has been corrected by performance of the first automated containment action and, if the negative laser condition has not been corrected by performance of the first automated containment action, to select as a next automated containment action a more invasive automated containment action from the plurality of automated containment actions and
• wherein the apparatus causes the laser system to perform the second automated containment action if the classifier determines that performance of the first automated containment action has not corrected the negative laser condition.

An apparatus for maintaining a laser system, the apparatus comprising:

• a first classifier that has been trained using a first data type;
• a second classifier that has been trained using data classified by the first classifier and a second data type, the second classifier being adapted to determine whether to perform an automated containment action;
• and
• a selector for selecting a selected automatic containment action to be performed if the second classifier determines to perform the automated containment action.
