In this Letter, we present the mode-locking operation of a 2.87 µm Ho^ 3+/Pr^ 3+ codoped
fluoride fiber laser, helped by the ultrafast nonlinear optical absorption behavior of gold …

Two-dimensional (2D) materials show great promise as saturable absorbers (SAs) for
ultrafast fiber lasers. However, the relatively low modulation depth and poor stability of some …

We experimentally demonstrate the ultrabroadband optical nonlinearity of indium tin oxide
nanocrystals (ITO NCs) in the mid-infrared regime. Especially, the ITO NCs show …

A Q-switched Er: ZBLAN fiber laser operating at 2.8 µm was realized by employing Sb as the
saturable material. The Sb material was deposited on a gold mirror by the magnetron …

Optical fiber-based photothermal devices show great promise for applications in in vivo
detection and therapy. The integration of sensors and actuators in one fiber is a feasible …

In this paper, we fabricate the bulk-like multilayer platinum diselenide (PtSe_2) and employ
it as saturable absorber (SA) for a passively Q-switched fiber laser operating at 2865 nm for …

Au nanocages (Au-NCs) have attracted wide attention as low-dimensional materials with
broadband absorption, ultrafast optical response, large third-order optical nonlinearity …

Mid-infrared (mid-IR) pulse modulation components are extremely limited and are not very
effective. By fabricating a novel broadband two-dimensional (2D) material, indium selenide …
