Summary form only given.To study the effects of high densities of excess free carriers on the optical transitions near the band edge of wurtzite GaN, nondegenerate nanosecond optical pump-probe transmission and reflection experiments have been performed on GaN thin films grown by metallo-organic chemical-vapor deposition (MOCVD) on (0001)-oriented sapphire. The large magnitude of the optical nonlinearities observed in our work suggests the possibility of new optoelectronic applications.
