In flexible food packaging, controlling material permeability is essential for preserving freshness and reducing global food waste. While Modified Atmosphere Packaging (MAP) regulates gas exchange between the product and its environment, its success relies entirely on the microscopic precision of film perforations. Spark Machinery has elevated this standard by integrating state-of-the-art machine…

A laser-based technology being developed at Adelaide University could soon help authorities detect deadly counterfeit alcohol, expose wine fraud and even identify dangerous chemicals inside sealed bottles – all without opening them.

Picosecond lasers with “burst-on-the-fly” pulsing can improve processing speed, via quality, and total cost-per-via for Ajinomoto Build-up Film (ABF) drilling. The post Optimizing ABF Drilling with Picosecond Lasers appeared first on Semiconductor Digest .

A rover powered in an unexpected way could soon head into the Moon’s most mysterious regions.

Laser-powered wireless hits 360 Gbps and uses half the energy of Wi-Fi Tiny lasers using light instead of radio waves could supercharge wireless speeds while cutting energy use. - Date: - April 2, 2026 - Source: - SPIE--International Society for Optics and Photonics - Summary: - A new breakthrough in wireless technology could dramatically boost internet speeds while cutting energy use—by switchin…

In addition to a large global network of communication cables, the ocean’s depths are home to a rich ecosystem of marine animals. These vital wires are susceptible to damage from earthquakes and tsunamis. Scientists that track this seismic activity encounter a hurdle since the Earth’s surface is more than 70% water. However, the wires present [..] The post Laser Technology Protects Global Communi…

The RP Photonics Encyclopedia covers the field of laser material processing quite comprehensively and carefully. For example, it explains underlying physical principles and resulting limitations.

It is discussed why laser diodes, in contrast to active fibers, cannot be made with very small refractive index contrast to obtain single-mode guidance in combination with very large mode areas. The key problem arises from the refractive index variations caused by the spatially varying carrier density.
