Sub-100 fs watt-level Kerr-lens mode-locked Yb:CaYAlO4 laser with a gigahertz repetition rate

Frontiers in Physics, 2023
We report a 1.04 GHz high-power Kerr-lens mode-locked Yb:CaYAlO4 laser pumped by a single-mode fiber laser at 976 nm. Based on a bow-tie cavity, stable unidirectional mode-locked operation is obtained with an output coupler of 1.6%.

All-fiber laser mode-locked by the acousto-optic modulation of a fiber Bragg grating in suspended core fiber [PDF]

, 2015
An ytterbium-doped fiber laser mode-locked by the interaction of a fiber Bragg grating and longitudinal acoustic waves in a suspended core fiber is experimentally investigated. An optimized design of an acousto-optic modulator is also proposed.

Wavelength-Switchable and Wavelength-Tunable All-Normal-Dispersion Mode-Locked Yb-Doped Fiber Laser Based on Single-Walled Carbon Nanotube Wall Paper Absorber

IEEE Photonics Journal, 2012
We demonstrate a compact wavelength-tunable and -switchable mode-locked Yb-doped fiber (YDF) laser based on single-walled carbon nanotube (SWCNT) wall paper absorber. Two mechanisms coexist in the fiber cavity.

Actively mode-locked Raman fiber laser

Optics Express, 2015
Active mode-locking of Raman fiber laser is experimentally investigated for the first time. An all fiber connected and polarization maintaining loop cavity of ~500 m long is pumped by a linearly polarized 1120 nm Yb fiber laser and modulated by an acousto-optic modulator.

Sub-100 fs pulse generation from dispersion-managed mode-locked Er:ZBLAN fiber laser at 2.8 μm

High Power Laser Science and Engineering
We demonstrate the sub-100 fs pulse generation from a dispersion-managed mode-locked Er:ZBLAN fiber laser at 2.8 μm. Both numerical simulation and experiment demonstrate that stretched-pulse and dissipative soliton mode lockings coexist in the near-zero ...

An investigation into Raman mode locking of fiber lasers

Optics Express, 2008
We present a detailed experimental and modeling study of fiber lasers passively mode locked using stimulated Raman scattering. We present experimental measurements of the mode locking behavior, and use the model to elucidate the nonlinear processes that create the intracavity pulses and determine the repetition rate and the order of fundamental and ...
