本文提出一种在激光等离子体中产生高丰度高电荷态离子的新途径，即通过共振光激发和碰撞电离混合过程来实现．模型计算表明，这一混合过程对提高高电荷态离子丰度的有效性．有关实验也证明这一过程的重要作用． In this paper, we propose a new way to generate highly abundant and highly charged ions in laser plasma, which is achieved by resonant photoexcitation and collision ionization mixing. Model calculations show that this mixing process is effective in increasing the abundance of highly charged ions. The experiment also proved the important role of this process.
