Abstract(in English) We grow layered semiconductor GaSe crystals by liquid phase epitaxy TDM-CVP for the difference frequency generation of THz wave. GaSe crystals have the wide transparency (λ = 0.6~20 μm), the large nonlinear optical coefficient (d22 = 54 pm/V @10.6 μm), and the high birefringence (no=2.9082, ne=2.5676 @1.06μm). For these superior properties, these crystals can generate high efficiency THz wave via difference frequency generation under collinear phase matching. In this study, Transition metal-doped or amphoteric impurity-doped GaSe crystals for the purpose of preventing free carrier absorption were grown by the same growth method. These crystals were evaluated by in comparison with the not-intentionally-doped GaSe crystals.
