摘要: 为了使全光纤结构啁啾脉冲放大实现超短激光的脉冲输出,采用色散补偿光纤对种子脉冲进行了展宽,利用普通单模光纤来实现放大后脉冲的压缩。对整体激光系统进行了理论分析和实验验证,获得了420fs的超短激光脉冲,平均功率达到1.81W。并利用周期极化的铌酸锂晶体对放大激光脉冲进行倍频,将激光波长拓展到近红外的780nm附近,光谱半峰全宽达到11nm。结果表明,在全光纤结构的掺铒光纤激光系统中,可以通过改变色散光纤的插入量对脉冲展宽和压缩过程中光谱畸变进行有效的控制。这一结果对于实现高功率的全光纤超短脉冲放大系统是有帮助的。

Abstract: In order to achieve ultrashort laser pulse output by all fiber chirped pulse amplification technique, dispersion compensation fiber and single mode fiber were used to stretch and compress the laser pulse in the time domain, respectively. The laser system was structured by three components: oscillator, pre-amplifier and main amplifier. The whole laser system was verified theoretically and experimentally. Ultrashort pulse laser with pulse duration of 420fs and average power of 1.81W was obtained. One piece of periodically poled lithium niobate crystal was employed to yield second-harmonic generation, so that the operating wavelength was extended to near infrared region centered at 780nm with full width at half maximum of 11nm. The results show that the spectra distortion can be precisely controlled during the whole amplification process by adjusting the insert dispersion. The study could be very helpful for study on high power all fiber ultrashort fiber amplifiers.
