I write and commission articles for the medical physics, and biophysics and bioengineering sections of the website. I did a PhD in molecular physics at Leeds University, followed by a postdoc in the medical physics department. I joined IOP Publishing in 1999, and in 2008 I became editor of the website medicalphysicsweb.

This year’s meeting, taking place from 3 to 8 March at the Minneapolis Convention Center, celebrates the 125th anniversary of the APS.</p> <p>“The annual APS March Meeting welcomes our diverse international community of over 13,000 scholars to share the excitement of new discoveries, establish new friendships, interests and collaborations, discuss and influence future directions and contribute to the expansion of human knowledge and endeavour,” says programme chair Paul Chaikin, from New York University.</p> <p>As well as the extensive programme of scientific sessions, the meeting includes several featured events. At a special session featuring Nobel laureates, recipients of the 2023 Nobel Prize for Physics and for Chemistry will discuss “Attosecond Physics, Quantum Dots, Human Rights”. Elsewhere, the Kavli Foundation Special Symposium looks at “Physics Far from Equilibrium”. There’s also Industry Day events focusing on industrial and applied physics research and careers, plus Future of Physics Days, designed to help undergraduates get the most out of their March Meeting experiences.</p> <p>Finally, there’s the exhibit hall to explore, where over 130 companies will be highlighting their latest devices and services for cutting-edge physics research. The exhibit will also feature poster sessions where scientists will share their latest findings, a job expo to meet potential employers and a graduate school fair. Read on to find out about some of the new product offerings that will be on show at this year’s technical exhibition.</p> <h3><strong>New lasers line up for emerging applications</strong></h3> <p>HÜBNER Photonics is showcasing an array of high-performance lasers that have been specifically developed for applications in quantum technology, nonlinear imaging and Raman spectroscopy.</p> <p>Designed for the life sciences market, the next generation of <a href="https://bit.ly/33TG3FS" rel="nofollow sponsored">VALO femtosecond lasers</a> – the Tidal – offers market-leading pulse durations of typically 40 fs, as well as 2 W output power.

The laser is easy to deploy and can be integrated into laser combiner options such as the C-FLEX or simply employed for stand-alone use in the laboratory. This 594 nm laser is specifically suitable for excitation of AF594, mCherry, mKate2 and other red fluorescent proteins.</p> <p>For Raman spectroscopy, the new Cobolt Disco 785 nm single-frequency laser delivers up to 500 mW in a perfect TEM00 beam. This new wavelength is an extension of the <a href="https://bit.ly/3tZ6nM5" rel="nofollow sponsored">Cobolt 05-01 Series</a> platform. Its innovative design delivers excellent wavelength stability, a linewidth of less than 100 kHz, and spectral purity better than 70 dB, providing the performance needed for high-resolution Raman spectroscopy measurements.</p> <p>HÜBNER Photonics is also highlighting a range of lasers for quantum technology applications. The Cobolt Qu-T Series is a family of compact, single frequency, tunable lasers operating at 707, 780 and 813 nm. Offering a course tunability of 2–5 nm, narrow mode-hop free tuning of less than 5 GHz, a linewidth of less than 100 kHz and powers of 500 mW, the Cobolt Qu-T Series lasers are ideal for quantum experiments based on atomic transitions and generation of entangled photon pairs through spontaneous parametric down-conversion.</p> <p>In addition, the new Ampheia Series of high-power fibre amplifiers are ideal for experiments in atom trapping. The Ampheia Series offers ultralow noise and single-frequency capability, while delivering 20, 40 and 50 W at 1064 nm in a perfect beam.</p> <ul> <li>For more information, visit HÜBNER Photonics at the APS March Meeting booth #1411</li> </ul> <h3><strong>Precision positioning and instrumentation for diverse physics applications</strong></h3> <p>For 25 years <a href="https://bit.ly/3S8wVCH" rel="nofollow sponsored">Mad City Labs</a> has provided precision instrumentation for research and industry applications, including nanopositioning systems, micropositioners, single-molecule microscopes and atomic-force microscopes (AFMs), as well as offering customized solutions.</p> <p>New for 2024 is the <a href="https://bit.ly/3SyVF7c" rel="nofollow sponsored">MadAFM</a>, a sample-scanning AFM that supports multiple microscopy modes for applications in materials characterization and the life sciences.

When used with AFMs, the nanopositioning systems provide true decoupled motion with virtually undetectable out-of-plane movement, while their precision and stability yields high positioning performance and control. These attributes make the nanopositioners ideal not only for AFMs, but for a range of applications in astronomy, photonics, physics, metrology and quantum sensing.</p> <p>The MadAFM joins the company’s existing line-up of instruments for <a href="http://www.madcitylabs.com/afm.html">AFM</a> and near-field scanning optical microscopy. Both optical deflection and resonant probe AFMs are available, with the latter designed to provide a flexible configuration for applications such as quantum sensing and scanning nitrogen-vacancy magnetometry.</p> <p>Other products from Mad City Labs include the RM21 single-molecule microscope, which offers direct optical pathway access, high stability and precision alignment. There’s also the unique MicroMirror TIRF system, which offers multi-colour total internal-reflection fluorescence microscopy with an excellent signal-to-noise ratio and efficient data collection, along with an array of options to support multiple single-molecule techniques.</p> <p>As well as offering turnkey instruments, Mad City Labs supplies standalone <a href="https://bit.ly/48DhPMh" rel="nofollow sponsored">micropositioning</a> products such as optical microscope stages, compact positioners for photonics, and the <a href="https://bit.ly/3U6RCBn" rel="nofollow sponsored">Mad-Deck</a> XYZ stage platform. These products use proprietary intelligent control to optimize stability and precision. The compatibility of the micropositioning products with the high-resolution nanopositioning systems allows users to develop solutions tailored to their specific applications.</p> <ul> <li>Find out more about Mad City Labs at the APS March Meeting booth #701</li> </ul> <p> </p> <div class="wrapper clearfix"> <div class="ajax__container fullwidth-newsletter-sign-up events-register-sign-up" style="border-color: #764992"> <form method="post" enctype="multipart/form-data" data-ajax="register" data-dest=".fullwidth-newsletter-sign-up"> <input type="hidden" name="signup" value="1"> <input type="hidden" name="shortform" value="1"> <input type="hidden" name="url" value="https://physicsworld.com/a/aps-march-meeting-connecting-physicists-from-around-the-globe"> <div class="fullwidth-newsletter-sign-up__email"> <div class="gf_browser_chrome gform_wrapper" id="gform_wrapper_1"> <div class="gform_heading"> <h3 class="gform_title">Want to read more?</h3> <span class="gform_description">Registration is free, quick and easy</span> <p><strong>Note:</strong> The verification e-mail to complete your account registration should arrive immediately.
