摘要：

High-contrast coherent population trapping signals were observed on the Cs D-1 line by use of a bichromatic linear polarized light (lin vertical bar vertical bar lin field). A maximum absorption contrast of about 10% was obtained. This was nearly twice as high as that measured with the standard configuration of bichromatic circularly polarized light (sigma - sigma field). The results are compared with density matrix calculations of 4 and 5 level systems. (C) 2009 Optical Society of America
