Burst pulse operation, the number of pulses in a packet, and pulse interval can be controlled by RF power modulation and pump control. The burst packet included up to 10 pulses at a pulse interval of 138 s. The pulse energy and pulse width of a single pulse in the packet were ~0.7 mJ and 70–150 ns, respectively. In addition, we have demonstrated that the envelope of the burst pulse train could be designed as required.","PeriodicalId":135970,"journal":{"name":"Solid State Lasers XXX: Technology and Devices","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123211287","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}
