Abstract: Aspects of the present disclosure provide techniques for performing a safety test of a laser diode associated with an ophthalmic surgical apparatus. An example method determining a measured slope efficiency of the laser diode based on a plurality of different current levels applied to an input of the laser diode and a plurality of different output power levels associated with the laser diode, determining an expected slope efficiency of the laser diode based on a measured operating temperature of the ophthalmic surgical apparatus, determining a result of the safety test of the laser diode based on the measured slope efficiency of the laser diode and the expected slope efficiency for the laser diode, and outputting an electrical signal indicating a result of the safety test of the laser diode.
