Abstract
A new theory is proposed for explaining the experimental results with intense short optical pulses. The theory is characterized by conjugate momentum interaction and especially large quantum enhancement factor and will unify the generation processes of coherent phonon formerly assigned as ISRS and DECP. It is applied to the instantaneous generation of lattice strain and the quantitative relation between the incident fluence and the resultant strain is shown.
