Gravitational modification of the Berry phase and some other effects induced by high-power lasers

Abstract

We study some effects when a probe light pulse propagates in the spacetime curved by the gravitational field of high-power laser pulses. The gravitational field produced by a high-power laser is calculated by using the linearized Einstein field equation under the weak field approximation. It is found that the gravitational modification of the photon Berry phase occurs when the probe light pulse transports in a uniform winding fiber in this gravitational background. We also find the gravitational redshifting and defocusing for the probe pulse caused by the gravitational field of the high-power lasers.
