英文摘要	We study the carrier-envelope-phase (CEP) effect of a few-cycle laser pulse on bound-bound transitions in helium in the high-frequency region. Specifically, for the one-photon transition from the 1(1)S to the 2(1)P state, the CEP effect increases as the frequency increases; while for the two-photon transition from the 1(1)S to the 3(1)D state, the CEP effect shows a peak at a frequency that is almost equal to the energy difference between the 1(1)S and 3(1)D states. By using a four-level model, we find that the CEP effect on the 1(1)S-2(1)P transition is attributed to the quantum interference between the positive-frequency and negative-frequency subpaths of the one-photon transition; whereas the CEP effect on the 1(1)S-3(1)D transition is attributed to the interference between the sum-frequency and difference-frequency components of the two-photon transition. These results indicate that the CEP effect can occur not only due to the interference between neighboring multiphoton-transition paths, but also due to the interference between two components inside one multiphoton-transition path. Therefore, this work, together with our previous work for the low-frequency region [Peng et al., Phys. Rev. A 82, 053407 (2010)], may provide a complete picture of the CEP effect on bound-bound transitions in the whole range of laser frequency.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000310259600005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Optics; Physics, Atomic, Molecular & Chemical; SCI(E); EI; 3; ARTICLE; 4; 86
