A detailed study is made of bifurcation of stationary (steady-state) and periodic solutions in the case of zero offset. It is shown that in the system under investigation there are two possible scenarios of transition to chaos for the selected parameters of a CO2/CH3I laser: period doubling and intermittency. An analysis is made of a change in the spectrum of the characteristic Lyapunov exponents in the chaotic lasing range. The predicted pulsed profiles are in good agreement with the experimental results. It is shown that in a certain range of parameters a laser with an absorber exhibits a generalized multistability.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80430340","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 method developed was used in making a holographic photothermoplastic disk with homogeneous storage characteristics. The promising aspects of designing a system based on a holographic photothermoplastic disk and using the parallel data-processing principle, such as an optical neural network and an optical correlator, are pointed out. The principle merit of these systems is their high data-processing rate with a large storage capacity for standard patterns. The possibilities are indicated of implementing low-frequency spatial image filtering by recording matched niters and holograms, of recording complex filters by superposition, and of local rerecording of data on a photothermoplastic disk.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90557425","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}

Results of a numerical simulation are presented. These demonstrate that the optical characteristics of lenses having a curvilinear contour are improved considerably. It is noted that hybrid planar optical systems free of the lowest-order aberrations can be constructed.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83748325","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}

These grooves improved the removal of heat from the central part of the active element responsible for generating the TEM00 mode and thus reduced the thermal deformation distorting the front of the light wave.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81973035","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}

It was possible to reach cooled atom temperatures right down to TR = 2k2/2MkB ≈ 10−6 K, determined by the recoil energy of the atom. The dependences of the temperature on the frequency difference between the light waves were investigated, for velocities near zero, and these were found to be in qualitative agreement with those observed experimentally. An expression for the beam diameter after compression by diverging waves was derived. Estimates of these effects are given for cases of practical importance.","PeriodicalId":21878,"journal":{"name":"Soviet Journal of Quantum Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76945098","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}
