Wavelength-tunable picosecond pulses from a passively mode-locked figure-eight Erbium-doped fiber laser with a Sagnac fiber filter [PDF]

Journal of the European Optical Society-Rapid Publications, 2008
We experimentally demonstrated a wavelength-tunable passively mode-locked Erbium-doped figure-eight fiber laser. Wide tunability is achieved using a high-birefringence (hi-bi) fiber Sagnac loop.

Energy Scaling of an Ultrafast All-PM-Fiber Laser Oscillator

IEEE Access, 2020
In this article we demonstrate the first, to the best of our knowledge, all-fiber self-starting laser oscillator consisting entirely of polarization-maintaining large mode area (PLMA) fibers mode-locked with nonlinear optical loop mirror (NOLM).

All-Normal-Dispersion Mode-Locked Fiber Laser With a Tunable Angle-Spliced Polarization-Maintaining Fiber Lyot Filter

IEEE Photonics Journal, 2021
We have proposed and implemented an all-polarization-maintaining mode-locked fiber laser operating in all-normal-dispersion regime based on nonlinear amplifying loop mirror.

Closing the Loop: High-Precision 3D Photofabrication in Living Tissues. [PDF]

Adv Sci (Weinh)
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Single and Multiple Pulse Pattern Formation in All-Normal All-PM Yb-Doped Fiber Laser Using a Nonlinear Optical Loop Mirror

IEEE Photonics Journal, 2022
We report the evolution of single-pulse and multi-pulse in a mode-locked all polarization-maintaining fiber laser based on a nonlinear optical loop mirror (NOLM). The main parameters of the laser were determined by numerically simulating the relationship

Studying the Operation of an All-PM Yb-Doped Fiber Laser Oscillator at Negative and Positive Net Cavity Dispersion

IEEE Access, 2022
Chirped fiber Bragg gratings in Yb-doped fiber lasers allow tuning the net cavity dispersion, thus enabling access to pulse dynamics beyond the typical all-normal-dispersion dissipative soliton regime.
