A method and system for laser surgery produces controlled laser pulses and simultaneously verifies that a sequence of pulses of prescribed energy are being delivered to the patient. A photo detector receives a predetermined portion of the energy of each treatment pulse. A separate monitoring computer compares an output signal from the photo detector corresponding to each treatment laser pulse with a reference value for that type of pulse obtained in a calibration sequence. Implementation in an ophthalmic laser surgery system is also disclosed.

[ I claim:] [6.]6. A system for monitoring laser pulses produced by a laser system in accordance with a predetermined treatment sequence and directed at the cornea of a patient to modify the cornea by photo ablation and for continuously verifying that the predetermined treatment sequence of pulses is being delivered to the patient comprising an electro-optic detector, a beam splitter for simultaneously directing one portion of the electromagnetic energy of the laser pulses along an optical path to the electro-optic detector and another portion of the energy of the pulse to the cornea of the patient, a diffuser in the optical path for receiving the laser pulse from the beam splitter, a fluorescent media in the optical path for converting the diffused, laser pulses to fluorescent light detected by the electro-optic detector; and a monitoring computer for comparing an output signal of the electro-optic detector with a reference value for the monitored pulse, said reference value being calculated in accordance with separately entered data indicative of the predetermined treatment sequence of different energy pulses and from signal values for such pulses measured by the electro-optic detector during a preliminary calibration.
