The dramatic progress in power-scaling of ultra-short pulse (USP) lasers and their continuous expansion use in industrial applications call for flexible and robust beam delivery systems (BDS) over several meters. Recently, a new branch of hollow-core photonic crystal fiber (HC-PCF) based on inhibited coupling (IC) mechanism has been proposed and successfully applied to demonstrate the delivery of...
We report on tapered inhibited coupling Kagome-fiber with a down-ratio as large as 2.4 while maintaining the hypocycloid-core shape. The insertion-loss of SMF spliced to tapered Kagome-fiber was measured with minimum of 0.48dB at 1550nm.
We report on 800nm laser-pulse delivery record by using inhibited coupling Kagome fiber. Strong spectral broadening and projected pulse compression down to ∼10fs were achieved with input 2.6mJ energy and 81GW peak power.
We report on design and fabrication of a new hypocycloid core-contour Kagome HC-PCF based on a triangular-like shaped core exhibiting smaller effective area and comparable confinement loss than previous hypocycloid core-contour Kagome fibers.
We review the recent progress on hypocycloid-shaped core-contour hollow-core photonic-crystal-fibre and its implementation in high optical-fields. Among the results we count self-compression of a femtosecond pulse to the sub-cycle cycle regime, a fibre aided material micromachining, and a generation of high power multiple-octave Raman optical comb.
Two major classes of hollow-core Photonic crystal fibres (HC-PCF) have emerged in the last decade. The first one relies on a cladding exhibiting a photonic bandgap in an appropriate index-frequency space. The salient features of these PBG guiding HC-PCF (PBG HC-PCF) are a relatively low transmission loss and a limited optical bandwidth [1]. The second one guides over a large optical bandwidth via...
We report on numerical and experimental results on the influence of cladding ring in hypocycloid-core Kagome HC-PCF. The number of rings has moderate effect on confinement loss whereas strong reduction in bend loss is demonstrated.
We describe an idealised "kagome-like" hollow-core fibre that supports a mode that is strictly localised (that is, exponentially confined, without leakage loss) despite the co-existence of cladding modes with the same effective index and symmetry.
We demonstrate what we believe is the first hollow fiber gas laser based on population inversion. A single-cell-defect Kagome fiber with a core diameter of about 40 microns was filled with a few torr of acetylene (12C2H2). Acetylene has absorption transitions in the attractive telecommunication C band region and recently lasing was observed at about 3 microns from a gas cell when optically pumped...
We present a very compact multi-line Raman-laser with broad spectral coverage from near-IR through to the much sought after yellow, deep blue and UV. Each line of the laser exhibits high power density which is ideal for forensics and biomedical applications requiring narrow-linewidth and high-power at several discrete wavelengths.
