The current state of the art in mid-infrared fiber lasers is reviewed in this chapter. The relevant fiber-host materials such as silicates, fluorides, chalcogenides, and ceramics, the fiber, pump, and resonator geometries, and the spectroscopic properties of rare-earth ions are introduced. Lasers at transitions ranging from 1.9 to 4 μm occurring in the

Electrically Pumped Mid‐Infrared Random Lasers
Advanced Materials, 2013 Electrically pumped random lasers, operating in the mid-infrared regime at λ ≈ 10 μm, are realized for the first time. Randomly distributed air holes are patterned onto a quantum cascade wafer emitting in the transverse-magnetic (TM) polarization. The advantage of employing TM polarized gain medium is that TM modes are more effectively confined in the ...

Lasers in Surgery and Medicine, 1986
AbstractFiber optics for carbon dioxide laser surgery have been in developmental research for the past ten years. An up‐to‐date presentation of infrared fiber optics as they pertain to laser surgery is presented. Optical properties such as intrinsic and extrinsic electronic absorption, multiphonon absorption, and scatter mechanisms are discussed.

Fractionated Mid-Infrared Resurfacing
Seminars in Cutaneous Medicine and Surgery, 2008Fractional resurfacing devices thermally alter microscopic treatment columns in the skin, leaving intervening areas between the columns untouched. Because only a fraction of the skin is being modified, untreated areas are able to rapidly repopulate the treatment columns to greatly reduce recovery time and adverse events. Mid-infrared fractional systems

Mid-infrared microfiber Bragg gratings
Optics Letters, 2020We report mid-infrared (mid-IR) Bragg gratings fabricated on sub-wavelength-diameter chalcogenide glass (ChG) microfibers. ChG microfibers with diameters around 3 µm are tapered drawn from A s 2 S 3 glass fibers, and the ...

Optical Fiber Communication Conference, 2015
Group IV and III–V semiconductor photonic devices are prime candidates for photonic and opto-electronic (OEIC) applications in the 1.8 to 5.0 µm infrared wavelength range. Si-based active photonics in the GeSn/SiGeSn heterosystem (LDs, PDs, LEDs, amplifiers, EOMs) offers the Si CMOS “foundry advantage” for high-volume low-cost OEIC manufacture. Two MIR

This chapter presents the scope and potentiality of Mid-infrared spectroscopy (MIRS) for food analysis. MIRS has a great potential to detect various components of food, and this technique holds great significance as it provides specific fingerprints for different food products. Mid-infrared range has an appropriate band in the spectrum for quantitative

Mid-infrared optical coherence tomography
Review of Scientific Instruments, 2007A time domain optical coherence tomography (OCT) system is described that uses mid-infrared light (6–8μm). To the best of our knowledge, this is the first OCT system that operates in the mid-infrared spectral region. It has been designed to characterize bioengineered tissues in terms of their structure and biochemical composition.

Infrared Physics, 1992
Abstract In this study the rise times of different fast mid-infrared detectors, i.e. of Ge photon-drag, pyroelectric and HgCdTe detectors are determined with the aid of 30 ps optical-free-induction-decay (OFID) 10 μm Co 2 -laser pulses. The measured rise times are all about 260 ps. This time is limited by the applied oscilloscope.
