Nonpolar a-plane ZnO film was successfully grown on (302)γ-LiAlO2 substrate by pulsed laser deposition. The temperature of substrate was 500℃, the film was pure nonpolar a-plane ZnO. The FWHM of the peak of near band emission in the PL spectrum was found to be only 115 meV. Both polarized transmission spectra and polarized Raman spectra revealed the in-plane anisotropy of the nonpolar ZnO film by the shift of absorption edge and the change of intensity of Raman E2 mode.
