摘　　要：利用自行研制的啁啾布拉格光纤光栅(CFBG)刻写系统完成CFBG样品制作,成功应用于光纤锁模振荡器和啁啾脉冲放大(CPA)系统中。振荡器可输出19.4 nm带宽、18 mW平均功率激光,并可压缩至143 fs,经时域展宽、功率放大、时域压缩后,脉冲宽度可至264 fs。实验结果初步证明了国产CFBG在飞秒激光系统应用的可行性。Applying the home made chirped fiber Bragg grating(CFBG) writing system, CFBGs are successfully fabricated and applied in fiber mode-locked oscillator and chirped pulse amplification(CPA) systems.The oscillator can output 19.4 nm bandwidth, 18 mW average power laser, and can be compressed to 143 fs. With pulse stretching, power amplification and compression, 264 fs pulse width can be obtained. The experimental results initially demonstrate the feasibility of the domestic CFBG in femtosecond laser systems.
