Controlling integral energy of a laser pulse in a hyperspectral, fluorescence, and laser mapping imaging system

A system comprising:

• an emitter comprising a plurality of sources of electromagnetic radiation, wherein the emitter cycles the plurality of sources on and off according to a pulse cycle pattern, and wherein the plurality of sources comprises:
• a visible source that pulses visible electromagnetic radiation within a first visible waveband that is 40 nm wide or less;
• and
• an infrared source that pulses infrared electromagnetic radiation within a first infrared waveband that is 40 nm wide or less;
• an intensity sensor that measures an intensity of electromagnetic radiation emitted by the emitter;
• and
• a controller in electronic communication with the emitter and the intensity sensor, wherein the controller comprises one or more processors executing instructions comprising:
• receiving an intensity value from the intensity sensor indicating an amount of energy emitted by the emitter;
• determining whether the intensity value is within a tolerance threshold with respect to a desired energy output for a corresponding pulse in the pulse cycle pattern;
• and
• in response to the intensity value not being within the tolerance threshold, adjusting one or more of a pulse intensity or a pulse duration for at least one future pulse in the pulse cycle pattern.
