From: Pressure-assisted sintering and characterization of Nd:YAG ceramic lasers
Plots for 0.9 mm, 1.5 at% Nd SPS- (black) and HPSPS-(red) processed samples, a comparison of (a) output power for the same absorbed power, (b) relative normalized power, calculated from three output power versus absorbed power plots, (c) slope efficiency and (d) threshold power.
