The initial data to be used for modelling are as follows: the size and the shape of a discharge-current pulse; discharge current-dependent radiated power; the dependence of radiated power upon the tuning control of a resonator at different pumping currents. The application of the above technique makes it possible to produce pulses of required shape and to select laser peak-efficiency operating conditions.","PeriodicalId":254986,"journal":{"name":"2010 International Conference on Advanced Optoelectronics and Lasers","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126527410","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}
