| Abstract(in English) | GaSe crystals have high birefringence(n_o=2.9082, n_e=2.5676 @1.06μm), wide transparency(0.6～20μm), and large nonlinear optical coefficient (d_<22> = 54 pm/V). For these superior properties, these crystals can generate high efficiency THz wave via difference frequency generation under collinear phase matching. THz generation efficiency of conventional Bridgman-grown GaSe crystals were decreased by thermal equilibrium point defects and non-stoichiometric composition. In this study, GaSe crystals for the THz wave generation were grown by the liquid phase epitaxy under controlled vapor pressure. Furthermore Fe-doped GaSe crystals for the purpose of prevention of free carrier absorption were grown by the same growth method. These crystals were evaluated by in comparison with the commercially available Bridgman grown crystals. |
