摘要
The line shape for atomic absorption of resonant laser radiation in a plasma is calculated. The shape turns out to depend on the temperature of the plasma ions, and can be used to determine this temperature. The cases of the linear and quadratic Stark effect are taken into account. A study is made of the change in the quantization axis of the atom in a strong laser field. This change results in a marked decrease in the absorption. Certain experimental aspects of laser plasma diagnostics are discussed.
