Abstract

The interactions of laser below moderate intensity with highly magnetized over-dense plasma are investigated analytically, which shows the capability of propagation into and probing of the over-dense plasma by right hand circularly polarized (RHCP) laser in the whistler mode, or when the axial magnetic field is above a threshold. The process of collisional heating is also studied, showing the dependence of heating depth and temperature on conditions of plasma, laser and magnetic field. A novel idea of direct laser ignition is brought up for the first time, where kJ/ns RHCP laser pulse will be used to heat up and ignite the compressed fuel directly with the assistance of strong axial magnetic field, different from other ignition schemes where laser should be first converted to shock wave, electron or ion beams.
