Abstract
Injection-seeded terahertz (THz)-wave parametric generators (is-TPGs) based on stimulated phonon-polariton scattering in MgO:LiNbO3 crystal are now well established as practical and widely-tunable sources of high-peak-power THz-wave radiation [1]. One of the key characteristics of these THz-wave sources is the parametric gain coefficient in MgO:LiNbO3 crystals. Theoretically, the gain coefficient has been studied by using the physical parameters of A1-symmetry mode at 248 cm-1 [2]. However, the absolute gain characterization still remains as an unsolved issue because no measurement has succeeded so far in directly determining the gain coefficient of stimulated phonon-polartion scattering.
