A passively mode-locked, figure-eight laser is formed of all normal dispersion fiber, eliminating the need for using anomalous dispersion fiber. Single server weighted fair queuing principles are extended to a multi-server system consisting of N servers each operating at a rate of r, referred to as a multi-server fair queuing system, to provide an output rate of Nr. The doping layer is disposed on the front surface. By reducing the cross-sectional area of the bore, the Reynolds number of fluids may be increased to the optimized level. The mount is adapted to attach an enrober head to the vessel, such that, when an enrober head is removed from an enrober and mounted on the apparatus, cleaning medium applied to elements of the enrober head can pass through those elements, through the mount and open top, and back into the vessel, cleaning the enrober head elements, and allowing the cleaning medium to be reapplied. The locked configuration secures the panels together, thereby securing the container in the three-dimensional configuration.
