Abstract Mid‐infrared (mid‐IR) ultrafast lasers are widely employed in biomedicine,
molecular spectroscopy, material processing, and nonlinear optics. With the improvement of …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

A paper is presented of artificial saturable absorbers as applied in fibre lasers. Shown are
the advantages and drawbacks of this saturable absorber type in comparison with material …

Ensuring self-driven mode-locking and broadband wavelength tuneability in all-fibre-
integrated femtosecond laser sources enables a new level of their versatility and extends …

We have successfully demonstrated the soliton mode-locked pulse generation in a 77 m
long erbium-doped fiber laser (EDFL) cavity using Poly (3, 4-ethylenedioxythiophene): poly …

We present the results of ex vivo exposure by an ultrafast all-fiber Holmium laser system to
porcine longissimus muscle tissues. A simple Ho-doped laser system generated ultrashort …

Laser cavities which can generate different types of ultrashort pulses are attractive for
practical applications and the study of pulse dynamics. Here, we report the first experimental …

Water plays a vital role in biological metabolism and it would be essential to trace the water
content non-invasively, such as leveraging the vibrational absorption peak of the O–H bond …

We report an investigation of dispersion management of an all-polarization-maintaining Er-
fiber oscillator mode-locked via a nonlinear amplification loop mirror in a figure-nine cavity …

We demonstrate a 41.6? MHz, 1.3 ps, 140 pJ Ho: fiber oscillator using a nonlinear
amplifying loop mirror (NALM) as saturable absorber. The oscillator is constructed entirely …
