Power measurements of the three EMS lasers (EMS-1, blue dots and blue lines; EMS-2, orange dots and orange lines; EMS-3, green dots and green lines): (a) measured power ($P_m$) for eight different powers set at the EMS laser units ($P_{set}$); (b) the difference between $P_m$ and $P_{set}$ at each set power; (c) deviation of $P_m$ compared to $P_{set}$ as a percentage. Black dashed lines illustrate ideal curves where $P_m$ equals $P_{set}$.
