The generation of SBS in a ring resonator can be considered as a lasing action, with the Stokes output downshifted in frequency by an amount equal to the Brillouin frequency. In the stationary case stimulated Brillouin scattering in a length of optical fiber can be described by the following partial differential equations for the slowly varying complex amplitudes of the pump wave E\u0000 p\u0000 and the backscattered first order Stokes wave E\u0000 B1\u0000 , with the wave amplitudes E\u0000 i\u0000 related to the intensities I\u0000 i\u0000 by I\u0000 i\u0000 = |E\u0000 i\u0000 |2 (i=p,B1) [1]: (1) In a ring resonator geometry as depicted in Fig. 1 the wave amplitudes at the ports of the directional coupler obey the relations [2] (2) where \u0000 \u0000 \u0000 \u0000 V\u0000 k\u0000 2\u0000 \u0000 \u0000 \u0000 is the coupler intensity radiation loss, K is the field coupling coefficient, and T is the field transmission coefficient.","PeriodicalId":441335,"journal":{"name":"Nonlinear Dynamics in Optical Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117137849","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}

The active medium of the laser is sodium dimer (Na2) vapor. The field patterns arise from the superposition of phase-locked higher-order transverse optical modes of the laser resonator. The astigmatically compensated ring resonator of the laser has the transverse-mode structure of a cylindrically symmetric, semi-confocal cavity. The narrow gain linewidth of the active medium permits to selectively excite groups of frequency-degenerate transverse resonator modes of common order. The shapes of the emitted field patterns are in agreement with the predictions of Brambilla et. al. (1990 NDOS conference, Afton, Oklahoma, paper ThB3).","PeriodicalId":441335,"journal":{"name":"Nonlinear Dynamics in Optical Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123307605","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}

Recent work has shown that the fully spatio-temporal propagation of a light wave envelope in a cubically nonlinear medium displays, in addition to the usual transverse structures, longitudinal dynamics which play an essential role in the evolution of the wave [1, 2, 3]. It has been suggested that the effect of dispersion coupled with self focusing causes short light pulses having beam waists much larger than their pulse length to display spectral characteristics typical of experimental observations of supercontinuum generation [1]. A recent computational effort has illustrated that the presence of dispersion can inhibit collapse due to two dimensional self focusing in normally dispersive media causing structure in the propagation direction as well as the transverse direction [3]. Finally, analysis of three dimensional propagation of light waves in anomalously dispersive media [4, 5] reveals a set of symmetric solutions which would exist in the intermediate state between collapse and dispersal. The practical stabilization of these light pulses is an open problem.","PeriodicalId":441335,"journal":{"name":"Nonlinear Dynamics in Optical Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122077854","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}

The methods have been able to stabilize both low dimensional experiments, such as electronic circuits [2] as well as high dimensional multimode chaotic lasers [3]. Controlling a chaotic system consists of stabilizing an unstable steady state or periodic orbit by having the system perform small amplitude fluctuations about some fixed parameter value. The OPF method is implemented by choosing the fluctuations so that the system is brought closer to the unstable orbit of interest. In the OGY method, the fluctuations are chosen so that the iterates fall on the stable manifold of the unstable orbit, thus keeping the dynamics in the neighborhood of the point of interest in phase space. Both methods are clearly related [4].","PeriodicalId":441335,"journal":{"name":"Nonlinear Dynamics in Optical Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126767320","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}
