報告摘要:

超短高能量脈沖光纖激光器在通信、傳感、精密機械加工等領域均有重要的應用。如何提高激光脈沖的功率和能量,掌握和利用超短脈沖光纖激光的複雜非線性,開展高能量、超寬帶全光纖超短脈沖激光應用的關鍵技術研究,成為了光纖脈沖激光的重要科學問題。我們總結了近年來國内外關于鎖模光纖激光器研究的一些關鍵技術和重要成果,分析了各類激光器及所産生脈沖的優缺點,重點讨論了不同色散區内光纖激光器的典型行為特征,從理論與實驗兩方面揭示了耗散孤子的産生機理、輸出特性及其演化規律。


Abstract: 

Ultra-short high-energy pulse fiber lasers can be found important applications in the areas of optic communication, sensing, precision machining, and material processing. How to increase the power and energy of the laser pulse, control and utilize the complex nonlinearity, and develop the key technologies for the applications of high-power, high-energy, and ultra-broadband all-fiber ultra-short pulse lasers become the important scientific issues for the exploration of new phenomena and schemes as well as the breakthrough of technical systems about fiber laser pulses. We briefly review some key techniques and important progresses about mode-locked fiber lasers, discuss the merits and drawbacks of various fiber lasers and pulses, also introduce our research results in the past several years about how to improve the performance of fiber lasers. We particularly discuss the typical behaviors of fiber lasers operating in different dispersion regimes, and demonstrate both experimentally and numerically the formation mechanisms, output features, and dynamic evolutions of dissipative solitons.
