Abstract :
Coherent anti-stokes Raman scattering (CARS) via terahertz-frequency optical phonon modes was successfully applied to the imaging of periodically poled lithium niobate crystals. Using spectral changes in the E-mode (50-1100 cm-1 = 1.5-33 THz), periodic structures of ferroelectric domains (period: 20 mum) were clearly mapped with CARS signals.
