Abstract A program to compute the two-step excitation of sodium atoms (3S _(1/2)→ 3P_(3/2)→ 4D_(5/2)) using the density-matrix formalism is presented. The BEACON program calculates population evolution and the number of photons emitted by fluorescence from the 3P _(3/2), 4D_(5/2), 4P_(3/2), 4S_(1/2)levels. Title of program: BEACON Catalogue Id: ADSX_v1_0 Nature of problem Resolution of the Bloch equations in the case of two-step laser excitation of sodium atoms. Versions of this program held in the CPC repository in Mendeley Data ADSX_v1_0; BEACON; 10.1016/j.cpc.2004.06.089 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
