Abstract: A laser module produces pulsed laser energy in a wavelength range of 495-580 nm based on duration, peak power, and interval parameter information. An envelope timer controls the total duration of all micropulses based on the duration and interval parameters via a pulse-width modulated (PWM) output to a micropulse timer, which in turn outputs a PWM micropulse signal. A light emitting diode driver outputs a laser current through a diode based on the micropulse signal and a dimming signal to produce the pulsed laser energy. The integrator compares a signal corresponding to a detected power level of the laser energy to a signal corresponding to the peak power parameter and outputs the dimming signal. The resulting micropulse durations are in the range of 50 to 300 microseconds for periods of about 2 milliseconds, with a duty cycle ranging from 5 to 15%. The overall pulse parameters are duration from 10 microseconds to 1.5 seconds, with periods of any value.
