High-Power Broadly Tunable 3- $\mu\hbox{m}$ Fiber Laser for the Measurement of Optical Fiber Loss

IEEE Photonics Journal, 2015
We demonstrate a $\hbox{Ho}^{3+}$, $\hbox{Pr}^{3+} $ co-doped fluoride fiber laser that produces an output power of 7.2 W, a 150-nm tuning range, and a narrow linewidth of $<\ 0.14$ nm using a power-scalable $\hbox{Yb}^{3+} $ fiber-laser-pumped ...

Cascade-Gain-Switching for Generating 3.5-$\mu$ m Nanosecond Pulses From Monolithic Fiber Lasers

IEEE Photonics Journal, 2018
We propose a novel laser configuration that can output 3.5- $\mu$m nanosecond laser pulses based on a simple and monolithic fiber structure. Cascade-gain-switching (CGS) converts the wavelength of nanosecond pulses from 1.55 to 3.5 $\mu$m by two ...

Stable mode-locked pulses from mid-infrared semiconductor lasers [PDF]

, 2009
We report the unequivocal demonstration of mid-infrared mode-locked pulses from a semiconductor laser. The train of short pulses was generated by actively modulating the current and hence the optical gain in a small section of an edge-emitting quantum ...
