GaN expitaxial films grown by pulsed laser deposition have been investigated by Raman scattering measurements. Room temperature electron concentrations and mobilities of films grown on 6H-SiC were estimated by A1(LO) mode analyses according to the theory of plasmon-coupled modes yielding values of about n=5xE+16cm^-3 and my=550cm^2/V.s, respectively. The Raman microprobe has served to explore the homogeneity of the films with respect to distributions of the residual strain and carrier concentration.
