Abstract
We have extended our previous measurements of the radiative recombination from photoexcited hot carriers in GaAs to excitation intensities as high as 6 × 106 W/cm2. We find that for I2×105 W/cm2, the carrier distribution is no longer Maxwellian. Another interesting result is that the emission extends well into the red region of the spectrum. Our results can be used to estimate the photoexcited carrier densities at such high intensities.
