Two-photon resonant third harmonic generation in carbon monoxide

Tunable coherent extreme ultraviolet radiation has been generated in CO by two-photon resonant third harmonic generation via the A(1) Pi(nu' = 4) <-- X-1 Sigma(+)(nu '' = 0) transition. The third harmonic spectrum exhibits resolved and improved rotational lines due to the expansion cooling of the molecular beam, The saturation and the phase-matching of the nonlinear process are also discussed.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1997XH74200011&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)3ARTICLE5360-3631
