    112-<italic>&#x03BC;</italic>J 180-fs Pulses at 1-kHz Repetition Rate From Yb-Doped Laser Based on Strictly All-Fiber CPA Structure by Decai Deng, Haitao Zhang, Qihang Gong, Linlu He, Jiaqi Zu

    Published 2019-01-01

    In this paper, we reported an Yb-doped, femtosecond, chirped pulse amplification laser based on strictly all-fiber structure. It operated at a low repetition rate of 1&#x00A0;kHz and adopted the synchronously pumping technology to suppress ASE and heat accumulation. A chirped fiber Bragg grating...

    Effect of Phase Relations on Speckle Pattern: Simulation and Measurement

    Effect of Phase Relations on Speckle Pattern: Simulation and Measurement by Linlu He, Haitao Zhang, Decai Deng, Qihang Gong, Jiaqi Zu, Kuo Meng

    Published 2019-01-01

    Speckle is an important phenomenon in various applications. It can be quantified by speckle contrast. However, at present, the influence of the phase relations among the various wavelengths on speckle contrast is rarely analyzed theoretically. Herein, a thorough method for numerically simulating the...
