Integrated sensors and transmitters of a wide variety of human physiological indicators have
recently emerged in the form of multimaterial optical fibers. The methods utilized in the …

We have successfully demonstrated a stable dual-wavelength Q-switched erbium-doped
fiber laser (EDFL) using a single mode fiber-multimode fiber-single mode fiber (SMF-MMF …

In this chapter, natural dyes that contain a quinoid group are overviewed. The classification
of the dyes has been made according to their basic chemical structure into benzoquinone …

In this letter, a titanium aluminum carbide (Ti3AlC2) coated D-shaped fiber is proposed and
demonstrated as a new saturable absorber (SA) for Q-switched laser pulse generation. In …

This paper describes the generation of mode locked pulses by an erbium-doped fiber laser
(EDFL) cavity with a Lawsone dye saturable absorber (SA). The Lawsone SA is made of a …

In this letter, we propose a passively Q-switched all-fiber laser and demonstrate how to
utilize a multimode double-clad Erbium–Ytterbium co-doped fiber as an active medium. The …

The manifold applications of pulsed fiber lasers are an evidence of the importance of laser
technology in science and engineering. Saturable absorbers (SA) play a key role in the …
