Coherent Phonon Decay of Raman Active Vibrations Within Oxide Groups of KTiOPO4

We present on decay of Raman active modes of potassium titanyl phosphate (KTiOPO 4 ) using a tunable ultrafast Coherent Anti-stokes Raman spectroscopy (CARS) system. Decay transients were around 70 dB signal spans with equivalent spectral resolution of better than 0.15 \text{cm}^{-1} and temporal re...

Summary:We present on decay of Raman active modes of potassium titanyl phosphate (KTiOPO 4 ) using a tunable ultrafast Coherent Anti-stokes Raman spectroscopy (CARS) system. Decay transients were around 70 dB signal spans with equivalent spectral resolution of better than 0.15 \text{cm}^{-1} and temporal resolution < 120 fs.
