Spatially resolved spontaneous emission intensity and spectrum were used to demonstrate the longitudinal-spatial-hole-burning (LSHB)-induced non-uniform carrier density along the resonator in high power lasers. The impact of high bias is analyzed. Spontaneous emission spectra are calculated to separate the effect of carrier density, and temperature.
