1. A controller for a surgical laser system, the surgical laser system including an array of laser diodes optically couplable to a delivery fiber, wherein the controller is configured to:
activate a first sub-array of the array of laser diodes to cause each laser diode of the first sub-array of laser diodes to output a first laser energy at a first wavelength range;
activate a second sub-array of the array of laser diodes to cause each laser diode of the second sub-array of laser diodes to output a second laser energy at a second wavelength range;
receive, via optical monitoring circuitry coupled to the array of laser diodes, an indication of an optical power of an output laser beam delivered to a target via the delivery fiber, wherein the output laser beam is a composite laser beam comprising the first laser energy output by the laser diodes of the first sub-array of laser diodes and the second laser energy output by the laser diodes of the second sub-array of laser diodes; and
activate, responsive to the optical power, a third sub-array of the array of laser diodes to cause each laser diode of the third sub-array to output a third laser energy at the first wavelength range or the second wavelength range; or
deactivate, responsive to the optical power, the first sub-array of laser diodes and/or the second sub-array of laser diodes.
