基于SESAM的掺铥锁模光纤激光器研究
Research on mode-locked thulium-doped fiber laser based on SESAM
摘要
Abstract
Aims:This paper aims to study the output characters of high-energy passive mode-locked thulium-doped fiber laser based on a semiconductor saturable absorption mirror(SESAM).Methods:By using the SESAM,a passive mode-locked thulium-doped fiber laser with an all-fiber structure was constructed using an all-fiber reflector and a fiber Bragg grating(FBG),respectively.Results:In the fiber laser using an all-fiber reflector,the output pulses with a central wavelength of 1 945 nm,a repetition frequency of 9.80 MHz and a single pulse energy of 9.46 nJ were obtained at the pump power of 900 mW.Based on this,another fiber laser structure in which the all-fiber reflector was replaced of a fiber Bragg grating(FBG)was built to reduce the threshold.The pulses with a central wavelength of 1 941.5 nm were obtained at the pump power of 210 mW.The power stability of RMS was less than 1％which confirmed the high stability of this laser source.Conclusions:The single pulse energy of the mode-locked fiber laser thus constructed can scale up to nJ in a stable mode-locking operation.关键词
