Figure 4.

Power measurements of the three K-lasers (K-1, blue dots and blue lines; K-2, orange dots and orange lines; K-3, green dots and green lines) used as continuous wave (CW) lasers. Measured power ($P_m$) for different powers set at the devices ($P_{set}$). (a–c) Measurements using the three wavelengths (800 nm, 905 nm, 970 nm) individually; (d) measurements using all diodes simultaneously. Black dashed lines illustrate ideal curves where $P_m$ equals $P_{set}$.
