Bichromatic two-photon coherent excitation of sodium to provide a dual-wavelength guidestar
Description
A bichromatic sodium guide star based on two-photon coherent excitation followed by cascade emission is considered. Results of density matrix computations, including Doppler averaging, are presented for both a three-level model and the full hyperfine structure of the sodium 3S , 3P , and 4S levels. These results indicate that the proposed scheme for a bichromatic guide star is feasible. (c) 2000 Optical Society of America
