在布鲁克海文国家实验室，激光离子源已经发展到提供重离子束通过使用等离子体产生与1064 nm的Nd：YAG激光照射到固体靶。激光能量被转移到目标材料并在表面上产生凹坑。然而，只有部分材料可以变成等离子体状态，而其他部分被认为是刚刚蒸发。由于靶材料中的热传播需要比典型的激光照射周期（其通常为几ns）更长的时间，因此仅层的一定深度可以有助于形成等离子体。结果，由于检测到基材Al离子，所以深度大于500 nm。另一方面，比较每个碳厚度情况的结果表明，表面碳层对产生等离子体没有贡献。
In Brookhaven National Laboratory, laser ion source has been developed to provide heavy ion beams by using plasma generation with 1064 nm Nd:YAG laser irradiation onto solid targets. The laser energy is transferred to the target material and creates a crater on the surface. However, only the partial material can be turned into plasma state and the other portion is considered to be just vaporized. Since heat propagation in the target material requires more than typical laser irradiation period, which is typically several ns, only the certain depth of the layers may contribute to form the plasma. As a result, the depth is more than 500 nm because the base material Al ions were detected. On the other hand, the result of comparing each carbon thickness case suggests that the surface carbon layer is not contributed to generate plasma.
