| Abstract: | The causes for the saturation of both the continuous-wave and the pulsed output power of broad-area laser diodes driven at
very high currents are investigated experimentally and theoretically. The decrease of the gain due to self-heating under continuous-wave
operation and spectral holeburning under pulsed operation as well as hetero-barrier carrier leakage and longitudinal spatial
holeburning are the dominant mechanisms limiting the maximum achievable output power. |
