Abstract: A laser system including a rack, a plurality of laser modules mounted in the rack to drive light through an optical fiber exiting the system, and a power distribution module to distribute electricity through circuit branches coupled to the laser modules is generally presented. In some embodiments, the rack includes a horizontal cross-member with a bottom rack flange extending vertically and defining a bottom of an opening in the rack. In some embodiments, the power distribution module includes an enclosure disposed in the rack opening, a face of the enclosure including a bottom lip to engage an edge of the bottom rack flange as a fulcrum point over a range to allow the enclosure to pivot between first and second pivot angles relative to the rack, one or more rails mounted within the enclosure, and one or more circuit components associated with each circuit branch disposed within the enclosure, each of the components including a rail-mount by which the component is affixed to the one or more rails, and a plurality of electrical cables coupling the power distribution module to the laser modules. In some embodiments, the one or more rails comprise a first and second rail bifurcating an interior volume of the enclosure into front and back volumes, and the one or more components further comprise a first component mounted to the first rail and occupying a portion of the front volume and a second component mounted to the second rail and occupying a portion the back volume. Other embodiments are also disclosed and claimed.

Abstract: An apparatus includes a plurality of laser system modules coupled to a communication bus that includes a module update bus, each laser system module including at least one module update port coupled to the module update bus and at least one micro controller unit (MCU) in communication with the module update port, wherein each laser system module is situated to receive a module update instruction over the module update bus based on a type identifier in a general purpose input/output (GPIO) register of the at least one MCU of the corresponding laser system module that indicates a laser system module type.
