ABSTRACT:
A pulsed laser system capable of operating in a plurality of modes for delivering a burst of laser pulses to a target wherein the pulse width of the laser pulses are automatically controlled in response to the mode selected. A special calibration procedure allows the system to determine the pulse width and pulse repetition rate when the laser is producing a predetermined power output level as measured by a power meter at the target site. Using calibrated pulse width and pulse repetition rate, the pulse width and pulse repetition rate of the laser pulses to be delivered to the target for any particular treatment burst can be determined. Means are provided for determining the energy delivered to the target for any particular treatment burst. A potentiometer coupled to a laser spot size control lense assembly provides a signal proportional to the spot size. From this signal and the energy delivered, the energy density can be calculated. A special REPEAT mode allows the operator to repeat automatically at preselected intervals the firing of bursts of laser pulses characterized by repetition rate, pulse width and exposure time. The bursts will be repeated for as long as the foot pedal is depressed.
