A new promising nonlinear optical crystal C25H25NO4S2 (HDB-T, P21 space group) exhibits significant macroscopic second-order optical nonlinearity about 1.5 times larger than that of the benchmark OH1 crystal benefiting from optimized orientated polar HDB cations. Widely tunable monochromatic terahertz-wave from 0.1 to 20 THz in the HDB-T crystal was realized for the first time.
一种新型有前景的非线性光学晶体C25H25NO4S2（HDB-T，P21空间群）表现出显著的宏观二阶光学非线性，由于优化取向的极性HDB阳离子，其非线性比基准OH1晶体大1.5倍左右。首次在HDB-T晶体中实现了0.1至20太赫兹范围内广泛可调谐的单色太赫兹波。
