Controlling of slope of carrier-envelope phase of few-cycle laser pulses on propagation distance near the focus

The effect of focusing geometry oil slope of carrier-envelope (CE) phase phi(CE) versus propagation distance from the focus in few-cycle laser pulses is investigated. The slope could be adjusted by changing the distance L between the waist of the incident beam and the lens. At the focus, partial derivative phi(CE)/partial derivative 9(z/zr) = 0 when L = 0, and partial derivative phi(CE)/partial derivative(z/zr) = -2 when L = infinity. The longer the distance L, the steeper the curve of the CE phase at the focus.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000246659400033&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)1ARTICLE51245-12472
