Abstract: Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.

Abstract: A medical laser system for outputting laser pulses includes at least one laser cavity, a rotating mirror, a user interface, and a controller. The controller is configured to receive at least one laser parameter associated with a laser pulse output by the system. The controller is configured to determine an average power level of the laser pulse based on the at least one laser parameter associated with the laser pulse. The controller is configured to determine a pulse width modulation (PWM) control signal based on at least one laser parameter. The controller is configured to generate the laser pulse based on the average power level and the PWM control signal, the laser pulse comprising at least one of a first shape, a second shape, or a third shape. Each of the first shape, the second shape, and the third shape of the laser pulse includes different pulse widths.
