Abstract
A laser diode system includes plurality of laser pumps, each of the plurality of laser pumps including a plurality of laser diode drivers and a plurality of laser diode elements, wherein each of the plurality of laser diode drivers is electrically coupled to power at least two of the plurality of laser diode elements. A combiner electrically is coupled to the plurality of laser diode elements to combine an output of each of the plurality of laser pumps to generate a combined output light. A controller identifies a failed laser pump or a failed laser diode element, receives an encoded key to gain access to the controller, and disables the failed laser pump or the failed laser diode element based at least in part on authenticating the encoded key.
