Summary form only given. High power mode-locked (ML) fiber lasers generating femtosecond pulses in telecom window near 1.55 μm is a field of growing interest due to the apparent success of all-normal dispersion (ANDi) fiber lasers generating chirped pulses in the wavelength region around 1 μm [1, 2]. Such lasers have a wide range of practical applications, from CARS and Terahertz spectroscopy to few-cycle pulse synthesis and telecommunications. In a majority of practical applications, short duration and high pulse energy are as important as long-term stability and usability. From this perspective the all-fiber lasers look the most appropriate due to their compact size, absence of complicated adjustments, high efficiency, intrinsic stability and perfect beam quality. In this paper, we demonstrate an all-fiber oscillator providing stable generation of highly-chirped dissipative solitons (DSs) at 1.55 μm. In order to provide stable NPE mode-locking, we applied the approach previously developed for Yb-doped all-fiber laser , namely, using a combination of polarization maintaining (PM) and non-PM parts to build the laser cavity and optimizing their lengths to achieve the best laser performance.
