Abstract
Femtosecond time-resolved coherent anti-Stokes Raman spectroscopy (CARS) is utilized to study the ultrafast vibrational dynamics in BBO crystals at room temperature. Time-resolved two-beam and three-beam CARS are detected. The vibrational dephasing time is analyzed and the changes of vibrational mode intensities with the polarization of pump pulses are observed.
► Ultrafast dynamics of BBO crystals was studied by femtosecond time-resolved CARS. ► Two-beam CARS is used to get duration of laser beams. ► Three-beam CARS was used to study coherent vibrational dynamics of BBO crystals. ► The intensity of vibrational modes was changed by polarization of pump pulses.
