“…However, with 74 µJ output pulse energy obtained, no damage to the fibre has been observed. This value is much higher than previously reported ultra-short pulse delivery using HC-PCF which is usually less than 10 µJ [36,37] . Furthermore, the 100 µJ pulse transported by the fibre corresponds to a fluence of 6 J/cm 2 , which is 3 times larger than the fused silica laser damage threshold with subpicosecond pulses.…”

We review the use of hollow-core photonic crystal fibre (HC-PCF) for high power laser beam delivery. A comparison of bandgap HC-PCF with Kagome-lattice HC-PCF on the geometry, guidance mechanism, and optical properties shows that the Kagome-type HC-PCF is an ideal host for high power laser beam transportation because of its large core size, low attenuation, broadband transmission, single-mode guidance, low dispersion and the ultra-low optical overlap between the core-guided modes and the silica core-surround. The power handling capability of Kagome-type HC-PCF is further experimentally demonstrated by millijoule nanosecond laser spark ignition and ∼100 µJ sub-picosecond laser pulse transportation and compression.

“…These are needed in diverse uses ranging from industrial materials processing, through to important applications in biology and medicine such as multi-photon microscopy and the treatment of various skin conditions. The improved performance of HC-PBGFs relative to solid fibres has been proven in experiments demonstrating the delivery of nanosecond pulse at ~mJ pulse energies (over greater distances than possible in solid fibres) [107], as well as in experiments in both the ps [108] and fs regimes [109,110]. ARFs also compete with HC-PBGFs in these applications, with HC-PBGFs providing advantages with regard to loss and bend loss (a particularly important feature for laser beam delivery) and with ARFs offering benefits in terms of the delivery of shorter pulses due to the inherently lower and flatter dispersion over broad bandwidths and the increased core sizes possible.…”

Since the early conceptual and practical demonstrations in the late 1990s, Hollow-Core Photonic Band Gap Fibres (HC-PBGFs) have attracted huge interest by virtue of their promise to deliver a unique range of optical properties that are simply not possible in conventional fibre types. HC-PBGFs have the potential to overcome some of the fundamental limitations of solid fibres promising, for example, reduced transmission loss, lower nonlinearity, higher damage thresholds and lower latency, amongst others. They also provide a unique medium for a range of light: matter interactions of various forms, particularly for gaseous media. In this paper we review the current status of the field, including the latest developments in the understanding of the basic guidance mechanisms in these fibres and the unique properties they can exhibit. We also review the latest advances in terms of fibre fabrication and characterisation, before describing some of the most important applications of the technology, focusing in particular on their use in gas-based fibre optics and in optical communications.

Abstract. The process of medical device innovation involves an iterative method that focuses on designing innovative, device-oriented solutions that address unmet clinical needs. This process has been applied to the field of biophotonics with many notable successes. Device innovation begins with identifying an unmet clinical need and evaluating this need through a variety of lenses, including currently existing solutions for the need, stakeholders who are interested in the need, and the market that will support an innovative solution. Only once the clinical need is understood in detail can the invention process begin. The ideation phase often involves multiple levels of brainstorming and prototyping with the aim of addressing technical and clinical questions early and in a cost-efficient manner. Once potential solutions are found, they are tested against a number of known translational factors, including intellectual property, regulatory, and reimbursement landscapes. Only when the solution matches the clinical need, the next phase of building a "to market" strategy should begin. Most aspects of the innovation process can be conducted relatively quickly and without significant capital expense. This white paper focuses on key points of the medical device innovation method and how the field of biophotonics has been applied within this framework to generate clinical and commercial success.
