Detecting problems of a laser beam of a laser system

An ophthalmic laser system, comprising:

• a laser system configured to:
• access a planned test pattern of a planned laser spot, the planned laser spot having one or more planned beam features;
• and
• direct a laser beam towards a test target located at a target plane according to the planned test pattern to yield an actual test pattern of an actual laser spot on the test target, the actual laser spot corresponding to the planned laser spot, the actual laser spot having one or more actual beam features, the laser system comprising:
• a laser source configured to generate the laser beam;
• and
• one or more beam control devices configured to guide the laser beam towards the test target;
• an imaging system comprising one or more digital cameras configured to generate a digital image of the actual test pattern of the actual laser spot;
• and
• a computer configured to analyze the digital image to:
• compare the actual laser spot to the planned laser spot;
• detect one or more deviations of the one or more actual beam features from the one or more planned beam features;
• identify one or more issues indicated by the one or more deviations;
• and
• provide output in response to the one or more issues.
