This paper, studies the influence of laser on the stopping power of a carbon ion in a two-component plasma, with emphasis on the effects of different laser amplitude, laser frequency, laser angle, plasma density, and plasma temperature on the stopping power based on the linearized Vlasov-Poisson model and molecular dynamics simulation. The research results show that the influence of laser on stopping power is very obvious in all the projectile region. In the low energy region (the magnitude of incident velocity is 0-0.1 plasma electron thermal velocity), the energy loss of the carbon ion mainly comes from the contribution of ions in the plasma, especially when the incident velocity is around the plasma ion thermal velocity, the first peak of stopping power occurs. In the medium and high energy region (the magnitude of incident velocity is greater than 0.1 plasma electron thermal velocity), the energy loss of the carbon ion mainly comes from the contribution of electrons in the plasma, especially when the magnitude of incident velocity is around 1.5 times the plasma electron thermal velocity, the second peak of stopping power occurs. The bimodal structure of the stopping power of the carbon ion in the plasma reflects the contribution of ions and electrons to the stopping power in different energy regions. On the other hand, the increase of laser intensity or laser frequency can decrease the stopping power of the carbon ion. The stopping power will be enhanced with the increase of plasma density or the decrease of electron temperature. Such an enhancement is more significant for stopping power for the low energy peak caused by ions compared to high energy peak caused by electrons.
