“…In doing this work we identified additional parasitic modes guided due to bandgap/low density of states effects capable of degrading the mode quality and which may limit the utility of such fibers in certain instances [16]. It is to be appreciated that the use of ESM fibers in additional wavelength regimes has also become the focus of considerable attention with the first reports of such fibers being made in new materials such as Tellurite glass (transparent at wavelengths up to 5ȝm) [17] and in silver halides (capable of guiding light at wavelength beyond 20ȝm) [18]. As well as being of interest for high power laser delivery, such fibers are of use in applications such as modal filtering in spaceborne astronomy [19], and broadband mid-IR supercontinuum generation where the large effective area is helpful since it allows SC generation at high pulse energies [20].…”

Abstract:We report recent advances in the development of fibers for the delivery of both single and heavily multimode laser beams in spectral regimes spanning the visible to mid-IR. IntroductionMicrostructured optical fiber (MOF) technology provides a powerful means to develop fibers with unique and enabling properties with potential uses spanning a very wide range of applications. Of all the opportunities provided by MOF technology amongst the most novel and intriguing are: (a) the possibility to guide light in air (through photonic band-gap or low density of state effects); (b) single mode guidance over extended spectral ranges (referred to as endlessly single mode (ESM) guidance); and (c) the fabrication of fibers with very much larger values of Numerical Aperture (NA) than possible using conventional fiber fabrication approaches. It is also important to realize that the MOF technology allows the fabrication of fibers using a single material -considerably enhancing the ease of producing fibers in new materials, such as polymers and compound glasses. This offers access to material properties that are substantially different to those of silica based glasses allowing, for example, fibers with transmission extending into the mid-IR, or ultrahigh values of nonlinearity per unit length. In the following sections we review recent progress in the design and fabrication of fibers that exploit several of these opportunities for the delivery of high power laser radiation and/or broadband light in different spectral regimes.

“…For example, we have recently developed structures capable of delivering both fundamental and second harmonic radiation from a pulsed Q-switched Nd:YAG laser as required for various direct-write materials processing applications [5]. The use of ESM fibers in additional wavelength regimes has also become the focus of considerable attention with the first reports of such fibers being made in new materials such as Tellurite glass (transparent at wavelengths up to 5μm) [6] and in silver halides (capable of guiding light at wavelength beyond 20μm) [7]. As well as being of interest for high power laser delivery, such fibers are of use in applications such as modal filtering in space-borne astronomy [8], and broadband mid-IR supercontinuum generation [6].…”
