Electronics Manufacturing Extends Spectrum of Integrated Photonics
Electronics Manufacturing Extends Spectrum of Integrated Photonics
Researchers from Nexus Photonics; (UC Santa Barbara); and Caltech have developed a technique to enable photonic chips to operate in the visible to near-infrared spectrum. The team's laser-coupling technique will make high-powered precision photonics orders of magnitude less expensive, and the technology holds potential for biomedical sciences through applications like biosensing and DNA sequencing. It could also open avenues in atomic physics and quantum research.

Needle-Shaped Beam Bolsters Range of Depth to Photoacoustic Method
Needle-Shaped Beam Bolsters Range of Depth to Photoacoustic Method
Researchers at Caltech have introduced an approach to photoacoustic microscopy (PAM) that uses a needle-shaped laser beam to extend the depth of field associated with the microscopy method. The technique, named NB-PAM (needle-shaped beam photoacoustic microscopy), delivered a depth of field that is nearly 14× greater than was previously achievable with PAM. With an increased depth of field, NB-PAM users acquired high-resolution images of samples even when their surface was uneven, and clearly imaged objects over a greater range of depths.

Atypical Accelerator Yields Free Electron Lasing in the Ultraviolet
Atypical Accelerator Yields Free Electron Lasing in the Ultraviolet
An international team led by Synchrotron SOLEIL, France, and Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Germany, has demonstrated seeded free electron lasing in the ultraviolet regime based on laser-plasma acceleration. Up to this point, free electron lasers (FELs), such as the the European X-Ray Free-Electron Laser (XFEL), in Germany, have been based on conventional electron accelerators, which makes them long and expensive. The advancement could allow researchers to build more compact systems, which would considerably expand the possible applications of FELs.

Fused Silica in Radiation Environments Fused Silica in Radiation Environments
Tue, Dec 13, 2022 1:00 PM - 2:00 PM EST
An increasingly wide range of applications need to be able to function in harsh environments, not only on space missions but also here on Earth, in particle detectors, for example. It is important to understand radiation's key processes and their effects on fused silica in order to design optical instrumentation that can avoid harm to its systems, enabling it to complete its mission. Eduard Klett of Heraeus Conamic provides an overview of fused silica as an optical material and how it is affected by different types and doses of radiation. He classifies types of radiation and discusses their causes. Presented by Heraeus Conamic.

High-Power Diode Laser Modules for Manufacturing and OEM Integration High-Power Diode Laser Modules for Manufacturing and OEM Integration
Wed, Dec 14, 2022 10:00 AM - 11:00 AM EST
High-power diode lasers have progressed significantly since their first appearance in the market. Today, these lasers are able to utilize high power levels and high-percentage electro-optical efficiencies for selected wavelengths. There are additional techniques that support the manufacture of special products, including line narrowing and spectral locking, with extraordinary results. Dr. Jörg Neukum, provides an overview of this technology, addressing wavelengths, cooling technologies, beam shaping, and power levels. He also presents selected examples of the realized performances. Sponsored by Coherent.
