The effect of self-focusing on the absorption and amplification of radiation
Abstract
Linearized theory is used to study the effect of self-focusing on the absorption and amplification of radiation; one-photon (or linear) absorption (or amplification) is used as an example. It is shown that the effect of self-focusing depends on several factors, including the radiation power, the ratio of absorption (or amplification) length to self-focusing length, and the decay instabilities of the radiation beam.
