Abstract

In this work, a high-energy and high peak power chirped pulse amplification system with near diffraction-limited beam quality based on tapered confined-doped fiber (TCF) is experimentally demonstrated. The TCF has a core numerical aperture of 0.07 with core/cladding diameter of 35/250 µm at the thin end and 56/400 μm at the thick end. With a backward-pumping configuration, a maximum single pulse energy of 177.9 μJ at a repetition rate of 504 kHz is realized, corresponding to an average power of 89.7 W. Through partially compensating for the accumulated nonlinear phase during the amplification process via adjusting the high order dispersion of the stretching chirped fiber Bragg grating, the duration of the amplified pulse is compressed to 401 fs with a pulse energy of 126.3 μJ and a peak power of 207 MW, which to the best of our knowledge represents the highest peak power ever reported from a monolithic ultrafast fiber laser. At the highest energy, the polarization extinction ratio and the M2 factor were respectively measured to be ~ 19 dB and 1.20. In addition, the corresponding intensity noise properties as well as the short- and long-term stability were also examined, verifying a stable operation of the system. It is believed that the demonstrated laser source could find important applications in, for example, advanced manufacturing and photomedicine.

单片锥形掺镱光纤啁啾脉冲放大器,输出126μJ和207MW飞秒激光,光束质量接近衍射极限。
本文实验证明了一种基于锥形约束掺杂光纤(TCF)的具有近衍射限制光束质量的高能高峰值功率啁啾脉冲放大系统。TCF的纤芯数值孔径为0.07,纤芯/包层直径在薄端为35/250µm,在厚端为56/400μm。在反向泵浦配置下,在504kHz的重复频率下实现了177.9μJ的最大单脉冲能量,对应于89.7W的平均功率。通过调整拉伸啁啾光纤布拉格光栅的高阶色散来部分补偿放大过程中累积的非线性相位,放大脉冲的持续时间被压缩到401fs,脉冲能量为126.3μJ,峰值功率为207MW,据我们所知,这代表了单片超快光纤激光器有史以来的最高峰值功率。在最高能量下,偏振消光比和M2因子分别测量为 ~ 19dB和1.20。此外,还检查了相应的强度噪声特性以及短期和长期稳定性,验证了系统的稳定运行。据信,所展示的激光源可以在先进制造和光医疗等领域找到重要应用。
