In this work we carry out an analytical study of pattern formation i n DOPO and degenerate lour-wave mixing (DFWM), which is complemented by numerical integration of the microscopic cquations of both systems. In the limit of small pump and signal detunings both systems are described by the real SwiftHohenberg equation (SHE). This broadens the range of similarities existing between DOPO and DFWM, which comprise both temporal instabilities and quantum properties. On the other hand the derivation of the SHE gives support io the already observed leading role of rolls in DOPO 111. l'he predictions about the stability of these patterns given by the SHE are in good agreement with numerical simulations. Moreover. i t has been recently shown that the SHE contains stable hexagons with an additional zero-mode [ 2 ] . which have been also found by numerical simulation. Contrarily, for small signal and large pump detunings the SHE is modified by the appearance of additional nonlinear tenns, which signals the existence of a nonlinear resonance (NLR). These additional ternis are however different iii DOPO and DFWM, limiting the similarities existing between both systems.","PeriodicalId":11780,"journal":{"name":"EQEC'96. 1996 European Quantum Electronic Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72576234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method offers thc prospect o f achieving a very high resolution, since the enclosed arca is larger than that of the corresponding conventional two-beam intcrfcrometcr. For our experimcnt, we usc a cesium atomic beam and two counterpropagating optical hcams in a e-0polarization configuration tuncd to the 6Sln(F=4)-6Pln(F=4) transition of the cesium DI -line. In a first laser pulse, ccsium atonis are optically pumped into a dark superposition of thc five even magnetic ground state sublevels (mr; = -4, -2, .... 4). The momenta of the atoms in these sublevels are 0,2hk, ... ,8hk relative to the momentum of the mF = -4 sublevel (Fig. I ) . The paths spatially separate for a time T, after which a second laser pulse splits each of the five paths further into five. A third pulse at time T after the second pulse closes all partial interferometers. To read out the interferometer, we detect the fluorescence emitted during the final pulse. Typical interferometer signals for T = 5 ps are shown in Fig. 2 as a function of the phase of the final pulse. With no additional phase, the atoms are already in a dark state at this time and no fluorescence is emitted. When the phase is varied, fluorescence can be observed since the atom is not dark any more for the light field. The experimental width of the dip presently is 0.32.2~. which is broader than the theoretical value of 0.18.2~. but clearly narrower than the value 0 . 5 2 ~ observed in a two-beam interferometer. With the use of colder atoms and magnetic shielding a fringe width close to the theoretical value should be possible. For much longer interaction times we expect a washing out of the fringes caused by a recoil phase shift that increases quadratically with the path number. When the total interaction time 2T is an integer multiple of the two-photon recoil energy, a revival of the original fringe pattem OCCUIS.","PeriodicalId":11780,"journal":{"name":"EQEC'96. 1996 European Quantum Electronic Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74176193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
