Multiple-pulse femtosecond optical excitation of ferroelectric materials is reviewed and new results are presented. The use of femtosecond pulse sequences to drive and amplify coherent phononpolariton responses is reviewed in connection with the objectives of elucidating nonlinear lattice and polarization dynamics and inducing domain switching and phase transitions. Preliminary results are presented on the use of pairs of femtosecond pulses to control the direction of induced polarization on ultrafast time scales. The induced polarization direction can be made to rotate or undergo other timedependent changes with extensive optical control.
