A theory of the coherent control of optical phonons by double-pulse excitation was modified for the calculation of a large detuning case such as diamond; we calculated the amplitude of the optical phonons without using a rotating-wave approximation. Additionally, we took the frequency chirping and non-Gaussian pulse shape into consideration. The coherent control of the amplitude of 40 THz optical phonons in diamond was demonstrated by using a pair of infrared pulses at a pump-pump delay between -10 and 120 fs, and analyzed by using the modified theory.
