Abstract Mid-infrared region (2–20​ μm) is an important region of electromagnetic spectrum.
Most of the molecules including CH 4, CO, NO, NO 2, C 6 H 6, TNT, NH 3, SF 6, HNO 3 …

Interest in mid-infrared spectroscopy instrumentation beyond classical FTIR using a thermal
light source has increased dramatically in recent years. Synchrotron, supercontinuum, and …

A turnkey fiber laser source generating high-quality pulses with a spectral sech shape and
Fourier transform-limited duration of order 100 fs widely tunable in the 1.6–2.65 μm range is …

We demonstrate broadband supercontinuum generation over two infrared octaves,
spanning from 1.3 to 5.3 μm, with an output power of 150 mW in robust step-index tellurite …

We demonstrate an integrated all-fiber mid-infrared (mid-IR) supercontinuum (SC) source
generated by a 1.95 μm master oscillator power amplifier system and a single-mode ZBLAN …

Diagnosis of diseases through exhalation is a new, noninvasive method. In this study, a new
photonic crystal fiber (PCF) has been proposed for detecting ammonia gas in breath. The …

We report on the design, fabrication, and experimental characterization of highly nonlinear
tellurite glass photonic crystal fibers with engineered normal dispersion characteristics for …

A simple design of a fiber laser system for generating high-quality pulses with a duration of
order 100 fs with ultrabroad wavelength tunability in the 2–5 μm range is discussed. This …
