2D wave structure induced by femtosecond laser pulse in semiconductor
We simulate interaction of a femtosecond laser pulse with semiconductor. As it is well known, under certain conditions the optical bistability (OB) takes place due to a nonlinear absorption of the optical energy, for example. We investigate the 2D wave process, occurring in such conditions and appearing because of instability of one from the bistable element states. Due to laser pulse propagating and electrons diffusion, the instability of the states of the optical radiation-semiconductor system causes the 2D wave propagation of free-electrons and ionized donors in semiconductor. This process can essentially change properties of the bistable element.
