摘要：

THz　time　domain　spectrum　of　KH2PO4　crystal　has　been　measured　in　the　range　from　0.2THz　to　1.6　THz.　Ultraviolet-visible　-infrared　spectra　have　been　measured　in　the　range　from　190　nm　to　1600nm　at　the　room　temperature.　The　energy　band　gap　Eg　of　KH2PO4　Crystal　is　5.90eV.　There　is　a　wide　band　of　the　phonon　absorption　in　the　KDP　crystal.　The　frequency　ωLO　of　the　longitudinal　optical　phonon　model　LO　is　about　1.291015Hz.　Frequency　ωTO　of　the　transverse　optical　phonon　model　TO　is　about　6.281012Hz.　©IEEE.
