We report the development of an approach to build compact waveguide lasers that operate
in the stable fundamental mode-locking regime with multigigahertz repetition rates. The …

We report a new solid-state waveguide laser generating picosecond pulses with a GHz
repetition rate, based on the use of graphene as a saturable absorber. Lasing at the main …

Sub-two-cycle optical pulses (5 fs) with spectra extending over more than one octave are
generated directly from a Kerr-lens modelocked (KLM) Ti: sapphire laser. Applications of this …

Actively mode‐locked lasers offer varying degrees of flexibility for a wider range of
applications than their passively modulated counterparts, due to their capability for …

We demonstrate, what is to our knowledge, the shortest pulses directly generated to date
from a solid-state laser, mode locked with a graphene saturable absorber (GSA). In the …

There is a growing interest in developing ultrafast laser sources around 2-μm wavelength
range. Here, we experimentally demonstrate a diode-pumped passively mode-locked Tm …
