Preparation of high-purity Pr 3+ doped Ge–As–Se–In–I glasses for active mid-infrared optics

Promising emission behavior in Pr 3+ /In selenide-chalcogenide-glass small-core step index fiber (SIF)

“…These losses are higher than the best loss results to date for Pr 3+ doped unstructured doped glass fiber, published recently in [28]. The results of [28] give confidence that background losses can be reduced to below the 1 dB m -1 limit that modeling suggests is desirable if efficient MIR fiber lasers are to be realized [36]. Fig.1(b)) and (c) undoped cladding-tube (section 2.2(a) and Fig.1(ii)).…”

“…purity Pr 3+ doped multi-component chalcogenide glasses can be found in [28][29][30], including the use of indium iodide to incorporate indium into Ge-As-Se-In-I [29] and Ge-Sb-Se-In-I [30] glasses.…”

“…One such ion is Pr 3+ in doped glasses, which have been proven to be excellent for several applications in optical devices such as up-converters, 26 solid state lasers 27,28 and optical bers. [29][30][31] The prime reason behind the use of Pr 3+ as an amplier is that it is not held back by ESA or parasitic emission. The non-radiative decay directs Pr 3+ to search for a host material with low phonon energy.…”

Experimental and numerical investigation to rationalize both near-infrared and mid-infrared spontaneous emission in Pr3+ doped selenide-chalcogenide fiber

“…Many devices for MIR applications based on chalcogenide glass fibers have been already demonstrated, which include supercontinuum sources, Raman lasers and compact sensing devices [19][20][21][22][23][24][25]. Also, an extensive effort has been invested into the design and modelling of MIR fiber-based and waveguide-based incoherent light sources based on Pr 3+ ion doped chalcogenide glass fibers [26][27][28][29][30][31].…”
