1. A method for controlling an output laser pulse signal of a medical device, the method comprising:
at a control device, defining a time duration of capacitive discharge of a capacitor bank to a laser device, wherein the time duration corresponds to an intended energy of the output laser pulse signal;
generating a pulse signal that defines a capacitive discharge event having a pulse width and a pulse period, wherein the pulse period is greater than the pulse width;
generating a control laser pulse signal that defines a plurality of sub-pulse control signals, wherein each of the sub-pulse control signals includes a plurality of the pulse signals and wherein each of the plurality of sub-pulse control signals are separated by a burst delay, wherein the burst delay is different than the difference of the separation of the plurality of sub-pulse control signals; and
modulating a duration of the burst delay to modify the capacitive discharge of the capacitor bank to the laser device during the time duration,
wherein the aggregate of the elapsed time of the sub-pulse control signals and the burst delays equals the time duration defined by the control device.
