Self-Reversed Emission Lines in Inhomogeneous Plasmasasma in the immediate environment of the radiator. The observed line contour outside the luminous source is the superposition of different line profiles corresponding to the radiation emitted in volume elements along a given optical path.

Emission Spectroscopyand electric fields, or waves excited in the plasma. This is certainly only possible to that extent that these parameters influence sufficiently the emitted electromagnetic radiation. For applications, on the other hand, one may simply be interested in the emitted spectrum of a specific discharge.

Discharge Light Sourcesabout 8×10. lumens would be generated. In turn, if this were distributed over the entire land area of the globe (7.2×10. sq cm), the net illumination would be 10. lumens/cm., 0.1 lumens/m. = 0.1 lux (ca 0.01 footcandle). This is about the illumination level of bright moonlight from a full moon.

High-Pressure Sodium (HPS) ARCSt required. The increasing cost of electrical power inevitably means that this lamp is being used to replace less efficient sources such as high-pressure mercury (~60 lm/W), despite the apparent longevity of the latter.

Radiation Transport in High Pressure Discharge LampsIn a gas discharge, radiation of various frequencies is emitted, absorbed and scattered in various regions throughout the plasma. In passing through the plasma it acts as a means of conveying energy from one region to another, and participates in associated phenomena such as excitation, ionization and dissociation.

Laser-Produced PlasmasThe invention of the laser has led to the generation of entirely new plasma phenomena, the first of which to be described was the production of a plasma in a gas by the action of light alone unaided by any other applied electric field.
