以GT-wave光纤为代表的泵浦增益一体化复合功能激光光纤是分布式侧面泵浦光纤技术的典型代表。GT-wave复合功能激光光纤具有良好的结构扩展性,泵浦注入路数可递增,泵浦光注入吸收和信号光增益放大都自然而均匀地实现,可有效热管理,转换效率高,稳定性好。英国SPI公司和美国IPG公司均采用此类光纤用于kW级高功率光纤激光器的研究和生产,我国相关研究单位也在逐步进入此研究领域并取得了初步进
The pump gain integration represented by GT-wave fiber is a typical representative of distributed side-pumped fiber technology. GT-wave composite function laser fiber has good structural expansibility, pump injection path can be increased, pump light injection and signal gain amplification are both natural and uniform amplification, effective thermal management, high conversion efficiency, stability it is good. British SPI company and the United States IPG companies are using such optical fiber for the kW level high-power fiber laser research and production, the relevant research institutes in China are gradually entering the field of research and has made preliminary
