Abstract: | A study is made of the generation of strong quasistatic magnetic fields by counterpropagating moderate-intensity laser pulses
of different frequencies in a low-density plasma. Strong magnetic fields are generated by small-scale large-amplitude plasma
waves excited at different frequencies by ponderomotive forces in the interaction region of laser pulses. It is shown that
magnetic fields are generated most efficiently under resonance conditions such that the frequency difference between laser
pulses coincides with the plasma frequency. The spatial distribution of quasistatic magnetic fields is investigated, and the
pattern of the contour lines of the electric current is calculated. |
