“…Furthermore, novel fiber-based IR sources are a potential growth area. There has been tremendous progress in IR supercontinuum generation from IR fibers [14,43,44,169,216,220,246,248,250,[468][469][470][471][472][473], but other nonlinear wavelength conversion schemes need also to be developed, such as Raman shifting and fourwave mixing. The high optical nonlinearity of IR glasses and the potential for dispersion engineering in high-index-contrast fibers may be exploited in producing IR laser combs [474][475][476].…”

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR spectrum, which is becoming increasingly more prominent in a variety of scientific disciplines and technological applications. Despite well-established efforts on the fabrication of IR fibers in past decades, a number of remarkable breakthroughs have recently rejuvenated the field-just as related areas in IR optical technology are reaching maturation. In this review, we describe both the history and recent developments in the design and fabrication of IR fibers, including IR glass and single-crystal fibers, multimaterial fibers, and fibers that exploit the transparency window of traditional crystalline semiconductors. This interdisciplinary review will be of interest to researchers in optics and photonics, materials science, and electrical engineering.

“…Different types of pulsed thulium-doped fiber-based laser systems, such as mode-locked [18,19], Q-switched and mode-locked [8,23] as well as gain-switched and modelocked [24,25] providing femtosecond [7] and picosecond [23,25] pulses, have been already proposed to pump fluoride fibers. In particular, CW model-locked fiber lasers followed by a cascade of amplifiers delivering optical pulses with pulse widths in the picoseconds range allow scaling output SC power to over 10 W, while being relatively easy in realization.…”

Broadband and top-flat mid-infrared supercontinuum generation with 3.52 W time-averaged power in a ZBLAN fiber directly pumped by a 2-µm mode-locked fiber laser and amplifier

Supercontinuum generation from 1.87 to 4.03 µm in a ZBLAN fiber is reported. A home-made passively mode-locked thulium-doped fiber laser and amplifier, providing 21.4-ps pulses at 81 MHz is used as a pump. The continuum output power is 3.52 W, of which 1.45 and 0.88 W corresponds to wavelengths longer than 3 and 3.5 µm, respectively. A spectrum flatness of 2 dB over a bandwidth of 1710 nm, from 2.02 to 3.73 µm, is also reported. This represents, to our knowledge, the best power conversion in the mid-infrared region and the best spectral flatness for high power supercontinuum generation in ZBLAN fibers directly pumped by 2-µm CW mode-locked fiber lasers and amplifiers.

High-peak-power single-oscillator actively Q-switched mode-locked Tm^3+-doped fiber laser and its application for high-average output power mid-IR supercontinuum generation in a ZBLAN fiber

A single-oscillator actively Q-switched mode-locked (QML) thulium-doped silica fiber laser is presented and used to pump a ZrF₄-BaF₂-LaF₃-AlF₃-NaF (ZBLAN) fiber for mid-infrared (mid-IR) supercontinuum (SC) generation. The fiber laser provided high-peak-power levels directly from the oscillator delivering single mode-locked pulse energies up to 48 μJ, being 2-4 orders of magnitude higher than conventional continuous wave mode-locked lasers. By pumping a ZBLAN fiber specially designed for high-output-power SC generation, 7.8 W have been achieved in all spectral bands with a spectrum extending to 4.2 μm.
