Mode-locked fiber laser with a fiber phase modulator [PDF]

Optics Letters, 1989
FM mode-locked operation of a single-mode Nd(3+)-doped fiber laser has been achieved with an integrated fiber phase modulator. The technique permits a low-loss cavity configuration, resulting in low threshold and high slope efficiency. Pulses of ~200-psec duration are observed at a repetition rate of 417 MHz with an average output power of 15 mW.

WS2 mode-locked ultrafast fiber laser [PDF]

Scientific Reports, 2015
Graphene-like two dimensional materials, such as WS2 and MoS2, are highly anisotropic layered compounds that have attracted growing interest from basic research to practical applications. Similar with MoS2, few-layer WS2 has remarkable physical properties. Here, we demonstrate for the first time that WS2 nanosheets exhibit ultrafast nonlinear saturable

Generation of 48 fs, 1 GHz Fundamentally Mode-Locked Pulses Directly from an Yb-doped “Solid-State Fiber Laser”

Photonics, 2023
We demonstrate a fundamentally mode-locked Yb-doped “solid-state fiber laser” with a repetition rate of 1 GHz and a pulse duration of 48 fs. The nonlinear-polarization-evolution (NPE) mode-locking of the “solid-state fiber laser” enables up to 286 mW of ...

Graphdiyne for Ultrashort Pulse Generation in an Erbium-Doped Hybrid Mode-Locked Fiber Laser

Frontiers in Physics, 2019
An erbium-doped hybrid passively mode-locked fiber laser based on few-layer graphdiyne (GDY) saturable absorber (SA) has been investigated for the first time. Hybrid mode-locked fiber laser is composed of non-linear polarization rotation (NPR) technology

Highly stable MXene (V2CTx)-based harmonic pulse generation

Nanophotonics, 2020
MXene as a novel two-dimensional (2D) material exhibits a lot of advantages in nonlinear optics. However, the common MXene, Ti3C2Tx and Ti2CTx nanosheets, easily suffer from degradation under ambient conditions, greatly limiting their practical ...

Dichromatic “Breather Molecules” in a Mode-Locked Fiber Laser

Physical Review Letters, 2023
Bound states of solitons (molecules) occur in various settings, playing an important role in the operation of fiber lasers, optical emulations, encoding, and communications. Soliton interactions are generally related to breathing dynamics in nonlinear dissipative systems, maintaining potential applications in spectroscopy.

Short pulse generation with 40 GHz passively-mode locked Q-dashed Fabry-Pérot laser [PDF]

, 2009
Generation of sub-picosecond pulses by a DC-biased passively mode-locked Fabry-Perot laser is demonstrated. By using a tunable band-pass filter, it is observed that the width of the generated pulses decreases in direct proportion to the optical modes ...
