Figure 6.6: SHG spectrum of 1.020 J.lm GaN sample in the s-injp-out polarization.
The angle of incidence is eo = 46°
significant for our 4.885 J.lm sample below a fundamental wavelength of 750 nm.
Figs. 6.6 and 6.7 display our s-in/p-out raw data from our undoped 1.020 J.lm and our
n-type 4.885 J.lm GaN samples. The data are referenced to the measured SHG from
quartz in the same polarization configuration. The discrepancy between the spectra
is due entirely to nonlinear interference effects, and is not due to differences in the
nonlinear susceptibility.
