Dynamic Stark Effect on Line Shapes in Laboratory and Fusion Plasma

Different forms of the Stark effect can affect the emission of line shapes in a plasma. Alongside the fluctuating microfield created by plasma ions and electrons, one often observes the fingerprints of oscillating electric fields. All these dynamic Stark effects result from random and collective motion of the particles but also from oscillating fields applied from outside the plasma by radiofrequency or laser sources. We here use a computer simulation to accurately capture the complex dynamics affecting the emission of a hydrogen atom in a laboratory or fusion plasma.
