Ultrafast laser sources operating in the mid-infrared (mid-IR) region, which contains the
characteristic fingerprint spectra of many important molecules and transparent windows of …

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 …

Germanium oxide (GeO2) and tellurium oxide (TeO2) based glasses are classed as the
heavy metal oxide glasses, with phonon energies ranging between 740cm− 1 and 880cm …

Transparent tellurite glass-ceramics are the new revolution in the photonics era. The novelty
of transparent tellurite glass-ceramics (TTGCs) originates from the formation of unique …

We experimentally demonstrated a passively mode-locked femtosecond laser by using a
graphene-based saturable absorber mirror (graphene SAM) in the spectral region of 2 μm …

Recent developments in laser sources operating in the mid-IR (3–8 μ m) have been
motivated by the numerous possibilities for both fundamental and applied research. One …

This review focuses on the engineering of the structural, thermal, optical and spectroscopic
properties of tellurium oxide (TeO2) glasses for their applications in fibre optic and …

Tm^ 3+ doped barium gallo-germanate (BGG) glass has emerged as a promising 2.0 μm
laser material offering excellent optical property. Unfortunately, low anti-crystallization ability …

Abstract Since the mid-(2–20 μm) and far-infrared (20–1000 μm) regions cover the vibration
and rotation characteristic “fingerprint” spectra of many gas molecules and three …

Single–walled carbon nanotube saturable absorbers were designed and fabricated for
passive mode-locking of bulk lasers operating in the 2 μm spectral range. Mode-locked …
