The dynamic Stark effect of excitons in GaN at 10 K with excitation well below the excitonic resonances was studied using nondegenerate femtosecond pump-probe spectroscopy with co-and cross-linear polarization configurations. In contrast to two-dimensional GaAs/AlGaAs quantum wells, which have Bloch

We present resonant femtosecond pump±probe reflectance measurements of excitons in high quality wurtzite GaN epilayers for a range of lattice temperatures and various pump intensities. From the density dependence of the excitonic bleaching we find that the Mott density is n Mott 2X2 Â 10 19 cm À3 .
