A mode-locked, dual-wavelength pumped 3.5 μm fiber laser using frequency shifted feedback utilizing an acousto-optic modulator is reported. Pulses of 3.8 ps with 9.7 nJ were obtained at a repetition rate of 37.75 MHz. The resulting peak power is 2.5

We report, to the best of our knowledge, the first mode-locked fiber laser to operate in the femtosecond regime well beyond 3 µm. The laser uses dual-wavelength pumping and nonlinear polarization rotation to produce 3.5 µm wavelength pulses with mi

We present our work towards a 3.5 µm Er3+:ZBLAN femto-second laser inscribed waveguide laser. The waveguide was made by extruding bulk ZBLAN glass into a slab for the first time, to the best of our knowledge. The slab was then cut and polished with

We report on a tunable mid-infrared erbium fiber laser mode-locked via frequency shifted-feedback provided by an acousto-optic tunable filter. Q-switched pulses were produced when the driving frequency of the acousto-optic tunable filter was square-w

The performance of mid-infrared Er3+-doped fiber lasers has dramatically improved in the last few years. In this paper, we present an overview of the progress in 3.5 ${\mu }\text{m}$ fiber lasers based on the dual-wavelength pumping approach. The cro

The performance of mid-infrared fiber lasers operating on the 3.5 μm transition in erbium has improved significantly since the first demonstration that dual wavelength pumping allowed efficient operation. In this contribution, we will discuss the pr

Short pulse operation of fiber lasers operating at wavelengths up 3 micron have been reported in recent years. At longer wavelengths, fiber lasers have only been demonstrated with a continuous operation mode. Short pulse operation in the mid-IR is ne
