The mid-infrared fiber lasers in the 2–3.5 μm spectral regions have been extensively applied
in many application fields, such as biomedicine, telecommunications, military and nonlinear …

In this brief review we consider the relatively new design of the pulsed fiber lasers, namely
lasers with the fiber saturable absorber (FSA). Main advantage of this design consists in a …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

A novel concept for an optical parametric oscillator based on four-wave mixing (FOPO) in an
optical fiber is presented. This setup has the ability of generating highly chirped signal and …

Chip-scale electrically pumped optical frequency combs (OFCs) are expected to play a
fundamental role in applications ranging from telecommunications to optical sensing. To …

We demonstrate sub-picosecond holmium-doped fiber laser mode-locked with a broadband
carbon nanotube saturable absorber. Ultrashort pulse operation has been obtained for the …

Three all-fiber Ho-doped lasers emitting in the range of 2050-2100 nm were fabricated. The
lasers were pumped by an Yb-doped fiber laser at 1147 nm with a power up to 35 W. For all …

Efficient holmium fiber lasers have been studied as attractive laser sources operating
around 2.1 μm. We report on holmium-doped silica fibers prepared by the modified chemical …

For the first time to our best knowledge we have used Ho-doped fiber amplifier to get
supercontinuum in the mid-IR range using all-fiber scheme. To pump the source Q-switched …

Abstract In this work, Nd/Al co-doped silica glass was prepared by laser additive
manufacturing. The doping concentrations of Nd 3+ and Al 3+ ions were measured to be …
