摘　　要：A certain class of exact solutions of Einstein Maxwell spacetime in general relativity is discussed to demonstrate that at the level of theory,when certain parametric resonance condition is met,the interaction of electromagnetic field with a gravitational wave will display certain Lyapunov instability and lead to exponential amplification of a gravitational wave train described by certain Newman-Penrose component of the Weyl curvature.In some way akin to a free electron laser in electromagnetic theory,by the conversion of electromagnetic energy into gravitational energy in a coherent way,the feasibility of generating a pulsed-laser-like intense beam of gravitational wave is displayed.
