Attenuated total internal reflection Fourier-transform infrared (ATR-FTIR) spectroscopy is a commonly used modality for measuring the spectra of highly absorbing liquids and solids. Previously, we combined broadband OPO-based mid-IR spectroscopy [1] with the use of a non-resonant hollow-core fibre (HCF) [2] to demonstrate heterodyne detection in a way that achieved common mode rejection of absorption features unique to the fibre transmission path [3]. We now extend this approach to enable simple, fibre-delivered ATR spectroscopy.

We report mid-infrared heterodyne spectroscopy of a sample located at the distal end of a hollow-core fiber, providing excellent sensitivity, eliminating distal-end electronics and enabling common-mode rejection of parasitic absorptions in the delivery path.

The role of photonics in healthcare is always pushing the boundaries of life science imaging and now more economical light sources are required, whilst achieving essential technical performance characteristics. In this presentation, we will consider the evolution of ultrafast laser sources over the last few years and demonstrate how important factors such as: microscopy integration, reliability and robustness are fostering new opportunities for ultrashort-pulse lasers to be adopted for a wide range of life science applications. Throughout the presentation, reference will be made to healthcare research conducted using fixed wavelength femtosecond sources for two-photon fluorescence microscopy and laser irradiation of nanoparticles.

We report the first nonlinear frequency conversion—specifically optical parametric oscillation—in OPGaP layers grown by hydride vapor-phase epitaxy on OPGaAs templates. A fan-out grating provides continuously wavelength-tunable broadband pulses covering 3.9–12 µm.

This article discusses the impact of trauma on cognitive development, linking this to a review of some of the literature available on the factors that enhance the therapeutic experience. Although the literature reviewed concerns general psychotherapy, further discussion is offered on the impact of the findings on music therapy. In response to the findings and the author’s continuing clinical music therapy work in the field of the impact of trauma, a pilot project is proposed using the Swanick-Chroma Assessment of Supportive Factors (S-CAF) questionnaire, which is based on Lambert’s four main factors of effective therapy: relationship/alliance, client characteristics, model of therapy, and expectancy. The S-CAF questionnaire can provide opportunities for professionals and the referred family to reflect on the levels of emotional and practical support available to them before and after the therapeutic process. It is proposed that the more the family feels emotionally supported, the greater the chance of success during and after therapy. A pilot research scheme is proposed to test the effectiveness of the S-CAF, with the creative arts therapists associated with Chroma (a creative arts therapies agency in the UK) undertaking the questionnaire as part of the therapeutic process (during assessment and evaluation). The results from the questionnaire will be used to inform the goals of the therapy, providing support to the family where needed.
