Abstract :
The cumulation dynamics and acceleration of ions in deuterium plasma by a focused ring laser pulse of femtosecond duration are theoretically investigated. The laser pulse is focused by the lens. The spatial structure of the ring laser pulse field in the vicinity of the lens focus is determined. The values of the cumulation coefficient, ion energy, and cumulation region dimension are obtained.
