Lasing without inversion in a four-level diamond system

doi:10.1088/1674-1056/21/12/124202

Abstract We study the lasing without inversion in a four-level diamond configuration in the case of incoherent pumping field within the framework of the bare-state basis. With the strong fields limit, we obtain the approximate steady-state solution, and discuss the dependence of population distribution and system gain on probe detuning and auxiliary field Rabi frequency.

Keywords: lasing without inversion four-level diamond system cyclic transition
