SPLITTING OF LO, TO MODE RAMAN SPCETRA OF SINGLE CRYSTAL KTiOPO4
KTiOPO4晶体纵横模劈裂的喇曼谱

The vibration spectra of single crystal KTiOPO4 was analysed using group method tnd measured in the frequency shift range of 50-1600cm-1 at room temperature. The Raman peaks of all LO, TO modes were obtained. Upon the result of LO-TO splitting, the effective charge, mode strength and static dielectric constant of polar modes of KTP single crystal were calculated.
