Abstract:

Absorption coefficient α(ν) and dielectric coefficient Ε(ν) of crystal Cr3+:LiSrAlF6 were obtained by THz Time Domain Spectroscopy (THz-TDS) in the range of 0.2-1.2THz. The infrared transmission spectrum R(κ) was measured from 6.7cm-1(0.2THz) to 4000cm-1. There is a band of the phonon absorption in the crystal. The frequency ωLO of the longitudinal optical phonon model LO is about 236 THz. And the ωTO of the transverse optical phonon model TO is about 9.42THz. ©IEEE.
