Abstract
The laser plasma interactions in the presence of strong magnetic field are studied by employing particle-in-cell simulations. Simulations show that the energy absorption of strong laser pulse is mainly characterized by the electron cyclotron resonance heating (ECRH) when the magnetic field is large enough. However, it is found that for a weaker magnetic field, a standing or moving soliton can be generated in some moderate laser intensity regions, greatly enhancing the laser absorption. The laser intensity for the soliton heating decreases as the magnetic field increases. Furthermore, the soliton position moves towards the front boundary when the laser intensity or magnetic field strength increases.
Highlights
The study of laser plasma interactions in the presence of strong magnetic field has become a hot research topic in fast ignition
It shows that the dependence of heating efficiency on laser intensities are quite different for different magnetic field strength
The absorption is dominated by the electron cyclotron resonance heating (ECRH) when the magnetic field strength is strong enough, e.g. comparable to the strength where ECRH occurs
