Interacting collective modes in a laser cavity

Creators

Description

Collective operators are defined for the quantized radiation field in a one-dimensional laser cavity coupled to a semi-infinite outside region and the overlaps of neighbouring collective modes are considered to show how they modify, in the linear appoximation, the time evolution of the radiation field below threshold. The model and procedure work directly within a continuous spectrum of modes and allow us to get an improved insight on the prescription for the laser field in single-mode operation. (Author)

Abstract (Portuguese)

Definem-se operadores coletivos para o campo de radiacao quantizado numa cavidade de laser unidimensional acoplada a uma regiao externa semi-infinita e consideram-se as superposicoes de modos coletivos vizinhos para mostrar como eles modificam, na aproximacao linear, a evolucao temporal do campo de radiacao abaixo do limiar. O modelo e procedimento trabalham diretamente dentro de um espectro continuo de modos e permite ter um sentimento melhorado sobre a prescricao para o campo de laser na operacao de modo simples. (L.C.)
