In this paper, we derive an expression of energy gain in a laser electron accelerator by using a general covariant coordinate transformation. It is pointed out that even when the external gravitational field, is absent, the electrons will still be additionally accelerated by the influence of background medium. In the vacunm case, the obtained results agree with those obtained by the Lorentz transformation.
