We present resonant femtosecond pumpΒ±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 Γ 10 19 cm Γ3 .

Time-resolved difference absorption spectra of J-aggregates were measured by femtosecond pump-probe spectroscopy. The induced absorption near the J-band at 20 K was assigned to the transitions from n-exciton states to ( n + 1 )-exciton states (n 2 1) . The decay time of the n( > 2)-exciton states is
