The simple plasma ball – it graces science museums and classrooms ... often created by heating a neutral gas or ionizing the gas in a strong electromagnetic field. The availability of free ...

In this process, a jet of plasma or ionized gas is ejected at high speeds, which melts and subsequently removes unwanted parts of materials from electrically conductive workpieces such as metals.

For example, a plume expanding into ambient gas of low pressure around 100 mTorr exhibits plume splitting and sharpening [1]. A definitive mechanistic explanation for laser-induced plasma plume ...
