我们已经研究了激光烧蚀等离子体的各种物种使用纳秒和亚纳秒激光的高和低电荷态离子的生产。我们发现，与亚纳秒激光，所产生的等离子体具有较长的尾巴，其中具有低电荷态离子确定的静电离子分析仪，即使在激光照射条件下的高电荷态离子的生产。这可能是由于等离子体羽流中的激光吸收不足造成的。这种性质可能适合于低电荷态离子的产生。我们使用纳秒激光和亚纳秒激光产生低电荷态离子，以研究使用锆靶产生等离子体的差异。
We have investigated laser ablation plasma of various species using nanosecond and sub-nanosecond lasers for both high and low charge state ion productions. We found that with sub-nanosecond laser, the generated plasma has a long tail which has low charge state ions determined by an electrostatic ion analyzer even under the laser irradiation condition for highly charged ion production. This can be caused by insufficient laser absorption in plasma plume. This property might be suitable for low charge state ion production. We used a nanosecond laser and a sub-nanosecond laser for low charge state ion production to investigate the difference of generated plasma using the Zirconium target.
