Abstract
A system for determining a characteristic of a laser includes a collection housing receiving a laser beam comprising a first pulse, a second pulse and a time period between the first pulse and the second pulse. A photon counting detector receives photons from the laser beam disposed to generate photon signals from the laser beam and generating a start signal. A fast diode generates a stop signal to provide a time reference of counted photons ns. A controller is coupled to the photon counting detector and the fast diode. The controller counts photons from the photon counting detector occurring during the time period between the first and second pulse and generates a first output signal corresponding to a power during the time period between the first pulse and the second pulse.
