摘要
We study generation of Čerenkov radiation by an ultrashort laser pulse propagating in the magnetized plasma across an external magnetic field basing on the analysis of the dispersion relation and numerical simulation in the case where the cyclotron frequency exceeds the plasma frequency. It is shown that the radiation with a frequency in the range from the plasma frequency to the cyclotron one and with an angle between the wavevector and propagation direction below 45° can escape the plasma. The radiation power increases with the magnetic field before reaching the maximum at the cyclotron frequency being of the order of the inverse of the laser pulse duration and starts decreasing afterwards. It is also observed that, with an increase in the field, the pattern of the radiation escaping from the plasma narrows, the generated pulse is shortened, and the pulse spectrum widens.
