Watt-Level Diode-End-Pumped Self-Mode-Locked Tm,Ho:LLF Laser
Photonics, 2023 A diode-end-pumped self-mode-locked Tm,Ho:LuLiF4 (LLF) laser is demonstrated for the first time, to the best of our knowledge. At the incident pump power of 3.4 W, the stable self-mode-locked operation of the Tm,Ho:LLF laser was realized without any ...

Generation of chirp-free picosecond pulses [PDF]
, 1977 The frequency spectrum of moderately chirped laser pulses depends upon the portion of the beam which is accepted by the spectrometer. Observation of the development of the chirp in a mode-locked pulse train allows to determine the small incipient chirp ...

Noise characterization of a pulse train generated by actively mode-locked lasers [PDF]
, 1996 We analyze the entire power spectrum of pulse trains generated by a continuously operating actively mode-locked laser in the presence of noise. We consider the effect of amplitude, pulse-shape, and timing-jitter fluctuations that are characterized by ...

Breathing dissipative solitons in mode-locked fiber lasers
Science Advances, 2019 Oscillating dissipative solitons and their bound states are captured in ultrafast lasers using real-time measurement techniques. Dissipative solitons are self-localized coherent structures arising from the balance between energy supply and dissipation ...

Photoniques, 2023 Mode-locked lasers are the fundamental source of ultrashort and ultraintense light pulses and a principal pathway for three Nobel Prize technologies: optical frequency combs, chirped pulse amplification, and attosecond light pulses. They are essential in routine and high-level applications such as refractive surgery, spectroscopy, or metrology.

Stability calculations for the ytterbium-doped fiber laser passively mode-locked through nonlinear polarization rotation [PDF]
, 2004 We investigate theoretically a fiber laser passively mode-locked with nonlinear polarization rotation. A unidirectional ring cavity is considered with a polarizer placed between two sets of a halfwave plate and a quarterwave plate.

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%.
