| Abstract: | Time-integrated spectra of three-halves harmonic emission from Au-disk irradiated by 1.053m m laser are experimentally studied. The wavelength shifts of red-shifted peak of the harmonic emission are measured in different angles. Fitting the experimental results to Barr's and Giulietti's theory shows that both theories can predict the correct dependence of the wavelength shift on the cosine of the emission angle while the former underestimates the electron temperature, and the later gives a result more close to that measured by x-ray. |
