.Structure multiformity of inverted Y-type four-level optical quantum coherent systems[J].Optoelectronics Letters,2010,6(1):65-68 Structure multiformity of inverted Y-type four-level optical quantum coherent systems 孟冬冬 Department;Physics;Tianjin;Polytechnic;University; Abstract:       According to the dipole transition selection rules and by choosing proper transition channels, it is found that the inverted Y-type four-level scheme can be classified into nine different 2nd-order subschemes when using corresponding laser fields, and they can be further classified into eighty 3rd-order subschemes in detail according to different exciting intensities that are applied in different channels. In this paper, the structure multiformity of inverted Y-type four-level scheme is discussed and the de... Hits: 3668 Download times: 201 View Full Text    Download reader
