Abstract:
A pulsed laser system, including:a laser;a power supply for supplying a train of input power pulses to the laser, wherein the laser produces a train of output beam pulses in response to the train of input power pulses;a user interface permitting the user to select a desired energy per output beam pulse;beam energy measurement means for generating a beam energy signal indicative of cumulative energy of one of said output beam pulses; andcontrol means for generating a termination control signal in response to determination that the cumulative energy of said one output beam pulse matches a threshold value, sending the termination control signal to the power supply to cause the power supply to terminate the input power pulse in response to said termination control signal, and generating the threshold value to have a particular value, T, representing a threshold output beam pulse energy lower than the user selected energy, E, of the output beam pulse, wherein the particular value T is determined based upon the selected energy E, thus compensating for inherent delay between generation of the control signal and termination of the output beam pulse in response thereto.
