(a) Passive losses as a function of ceramics length. Lasing efficiencies are noted for each sample. Blue and red represent samples that lased and sample that did not laser, respectively. (b) Slope efficiency as a function of passive losses for samples which lased. Different colors account for different sample lengths. Full and hollow notations represent SPS- and HPSPS-processed samples, respectively.
