Self-starting Nd-doped fiber Mamyshev oscillator near 920 nm using an intra-cavity SESAM
We demonstrate a femtosecond Mamyshev ring oscillator operating near 920 nm, based on W-type index profile double-clad Nd<sup>3+</sup>-doped polarization-maintaining (PM) fibers. Mode-locking is initiated using an intracavity SESAM to ensure reliable self-starting. This mode-locked fiber laser source delivers up to 7.1 nJ pulse energy at a repetition rate of 10.47 MHz, which is compressed down to 71 fs using a pair of gratings. An amplification stage utilizing optimized Nd-doped large mode area (LMA) fiber increases the pulse energy up to 105 nJ, though this results in longer compressed pulses.
