2High-power,electronically controlled source of user-defined vortex and vector light beams based on a few-mode fiber amplifier显示文摘Optical angular momentum(OAM)-based structured light beams provide an additional degree of freedom for practical applications ranging from optical communication to laser-based material processing. Many techniques exist for generating such beams within laser sources and these primarily rely upon the use of specially designed optical components that limit laser power scaling and ready tunability of the topological charge and polarization of the output OAM beams. Here we show that some of these limitations can be overcome by employing a computer controlled reflective phase-only spatial light modulator to adaptively tailor the input(and subsequent output) beam wavefront and polarization in a few-mode fiber amplifier. In this way modal-coupling-induced beam distortion within the fiber amplifier can be mitigated and we are able to generate at will any desired supported spatial mode guided in the fiber, including conventional linearly polarized(LP) modes, scalar OAM modes, and cylindrical vector modes, at average powers >10 W and with a peak power of >11 kW. Our results pave the way to the realization of practical high-power structured laser sources with tunable chirality and polarization.DI LIN JOEL CARPENTER YUTONG FENG YONGMIN JUNG SHAIF-UL ALAM DAVID J.RICHARDSON 2021Photonics Research2021,9,5:2

12Femtosecond laser fabrication of nanograting-based distributed fiber sensors for extreme environmental applications显示文摘The femtosecond laser has emerged as a powerful tool for micro-and nanoscale device fabrication. Through nonlinear ionization processes, nanometer-sized material modifications can be inscribed in transparent materials for device fabrication. This paper describes femtosecond precision inscription of nanograting in silica fiber cores to form both distributed and point fiber sensors for sensing applications in extreme environmental conditions. Through the use of scanning electron microscope imaging and laser processing optimization,high-temperature stable, Type II femtosecond laser modifications were continuously inscribed,point by point, with only an insertion loss at 1 d B m~(-1) or 0.001 d B per point sensor device.High-temperature performance of fiber sensors was tested at 1000℃, which showed a temperature fluctuation of ±5.5℃ over 5 days. The low laser-induced insertion loss in optical fibers enabled the fabrication of a 1.4 m, radiation-resilient distributed fiber sensor. The in-pile testing of the distributed fiber sensor further showed that fiber sensors can execute stable and distributed temperature measurements in extreme radiation environments. Overall, this paper demonstrates that femtosecond-laser-fabricated fiber sensors are suitable measurement devices for applications in extreme environments.Mohan Wang Kehao Zhao Jingyu Wu Yuqi Li Yang Yang Sheng Huang Jieru Zhao Thomas Tweedle David Carpenter Guiqiu Zheng Qingxu Yu Kevin P Chen 2021International Journal of Extreme Manufacturing2021,3,2:1

19Temporal bone anatomy characteristics in superior semicircular canal dehiscence显示文摘Introduction: Superior semicircular canal dehiscence(SCD) remains difficult to diagnose despite advances in high-resolution computed tomography(HRCT) imaging. We hypothesize possible associations between gross temporal bone anatomy and sub-millimeter pathology of the semicircular canals, which may supplement imaging and clinical suspicion. This pilot study investigates differences in gross temporal bone anatomic parameters between temporal bones with and without SCD.Methods: Records were reviewed for 18 patients referred to an otology clinic complaining of dizziness with normal caloric stimulation results indicative of non-vestibular findings. Eleven patients had normal temporal bone anatomy while seven had SCD. Three-dimensional reconstruction of every patient's temporal bone anatomy was created from patient-specific computational tomography images. Surface area(SA),volume(V), and SA to V ratios(SA:V) were computed across temporal bone anatomical parameters.Results: SCD temporal bones have significantly smaller V, and larger temporal bone SA. Mean(±SD) V was 21,484 ± 3,921 mm^3 in temporal bones without SCD and 16,343 ± 34,471 mm^3 for those with SCD. Their respective SA were 13,733 ± 1,603 mm^2 and 18,073 ± 3,002 mm^2.Temporal bone airspaces and lateral semicircular canals did not demonstrate significant differences where SCD was and was not present. Plots of MV_(warm)response against computed SCD temporal bone anatomic parameters(SA, V and SA:V) showed moderate to strong correlations:temporal bone SA:V(r= 0.64), temporal bone airspace V(r= 0.60), temporal bone airspace SA(r= 0.55), LSCC SA(r= 0.51), and LSCC-toTM Distance(r= 0.65).Conclusions: This analysis demonstrated that SCD is associated with decreased temporal bone volume and density. The defect in SCD does not appear to influence caloric responses.Marrigje A. de Jong David J. Carpenter David M. Kaylie Erin G. Piker Dennis O. Frank-Ito 2017Journal of Otology2017,12,4:1
