摘要：
We investigate the electromagnetically induced grating in a Lambda-type three-level atomic system with a microwave field coupling the two ground states. The results show that the intensity of diffraction, especially the first-order diffraction, is increased remarkably due to the modulation and gain of the microwave field. If the parameters of the system are chosen properly, the intensity of the first-order diffraction goes up exponentially as the microwave intensity increases.
