THz field spectra at Z (a) and X (b) mode orientation at different temperatures. The pump wavelength is 1325 nm. Solid lines represent experimental data; dashed lines represent phase matching approximations using experimental transmission spectra data. The insets represent the comparison of THz radiation spectra generated at 293K in the case of two pump laser wavelengths: 1325 nm and 797 nm.
