In this paper, we have investigated the lifetime, mobility and effective mass of polaron and bipolaron in graphene under laser field by using the well-known Lee–Low–Pines transformations. In this study, it is seen that the laser affects mostly the dynamics parameters of polaron and bipolaron in graphene. We found that the laser reduces the lifetime of the polaron in the fundamental state and increases it in its excited state. The excited polaron survives to the effects of laser more than the excited bipolaron. However, the polaron and bipolaron in the fundamental state have about the same laser sensitivity. The polaron and bipolaron in graphene become less heavy; under laser, they get massless. Polaron and bipolaron present a good mobility as charge carriers in the presence of laser effect.

在本文中，我们使用著名的Lee–Low–Pines变换研究了石墨烯中极化子和双极化子在石墨烯中的寿命，迁移率和有效质量。在这项研究中，可以看出激光主要影响石墨烯中极化子和双极化子的动力学参数。我们发现，激光会缩短基本状态下极化子的寿命，并增加其激发态下的极化子寿命。受激极化子比受激双极化子在激光作用下的寿命更长。然而，处于基本状态的极化子和双极化子具有大约相同的激光灵敏度。石墨烯中的极化子和双极化子变轻。在激光作用下，它们变得无质量。在存在激光效应的情况下，极化子和双极化子作为电荷载流子表现出良好的迁移率。
