Abstract

Fock space multi-reference coupled cluster (FSMRCC) linear response approach is used to calculate first static hyperpolarizability of the few low lying excited states of lithium aluminum hydride ( LiAlH4 ) to predict its excited state nonlinear optical activity. It is observed that though
lithium aluminum hydride does not show strong nonlinear optical activity at its ground state, it is highly active in its low-lying excited states. Using this property of LiAlH4 , a new technique is described to generate mixed frequency laser which is a laser of new kind, reported here for the first
time. This also helps to generate a laser with shorter pulse duration compare to the laser pulse duration used as incident radiation. Third order energy response properties of excited states of a closed shell molecule in analytical FSMRCC approach are also reported here for the first time.
