TL;DR: This result represents, to the best of the authors' knowledge, the shortest pulse duration ever achieved in bulk Er lasers Q-switched by 2D materials.

TL;DR: In this article, a SESAM mode-locked Tm,Ho:CALGO laser emitting at 2.015 µm due to the combined gain of both dopants generates pulses as short as 52 fs with a maximum output power of 376 mW at 86 MHz.

TL;DR: In this paper, a technique for inkjet-printing of graphene saturable absorbers (SAs) for ~2-μm bulk and waveguide lasers is presented based on distillation-assisted solvent exchange to fabricate high-concentration graphene inks, this technique is capable of producing few-layer graphene films of arbitrary shape.

TL;DR: In this article, the first Tm3+-doped double tungstate waveguide laser passively Q-switched by a graphene saturable absorber using a 12.4 µm-thick 3 at.

TL;DR: The ZnO NRs grown on various optical surfaces are promising broadband saturable absorbers for nanosecond near-IR lasers in bulk and waveguide geometries and at low saturation intensity and high fraction of the saturable losses.
