🚀 Advancing Precision Glass Micromachining with Ultrashort Laser Pulses 🚀 We’re excited to share our latest breakthrough in precision glass micromachining! Our technology, now at a mature stage, leverages ultrashort laser pulses to achieve micron-level accuracy in drilling, cutting, and ablation of various glass types. 🌟 Key Highlights: 🔹 Bessel Beams: Utilizing their invariant focal zone, Bessel beams create elongated channels in transparent materials, enhancing cutting efficiency over standard Gaussian beams. 🔹 Innovative Approach: We employ asymmetric phase-split diffractive axicon masks and geometric phase optical elements, crafted with transparent nanogratings, to generate high-power asymmetric Bessel-like beams. 🔹 Applications: This method is pivotal for applications like glass stealth dicing, offering optimal beam-shaping performance. Stay tuned as we continue to push the boundaries of laser micromachining technology! 💡🔬 #LaserTechnology #Micromachining #Innovation #GlassCutting #BesselBeams #PrecisionEngineering https://lnkd.in/d_SeZEui

Omnidirectional vacuum coating refers to a process in which thin films are uniformly deposited onto all surfaces of an object in a vacuum environment, using techniques such as evaporation and sputtering. This method is typically used to enhance the surface properties of the object, such as wear resistance, anti-reflectivity, conductivity, and more. In the optical field, omnidirectional vacuum coating is commonly used to produce high-quality optical components, such as lenses, optical filters, and prisms, especially in applications that require high precision and quality, such as laser equipment, microscopes, and camera lenses. This method can provide optical components with high transmission or anti-reflection coatings, improving their performance and extending their lifespan.#lens #vacuumcoating #optics #physics

New Publication with APE's high contrast autocorrelator Did you know that different types of lasers have different pulse pedestals in terms of pulse energy? For some lasers, this pedestal can be a significant portion of the total pulse energy, as much as 40%, and as long as a few hundred picoseconds (see figure). To find out how much pedestal a laser has, you need a high-contrast autocorrelator like the pulseCheck SM Type 2. With it, you can measure pulse contrast up to seven orders of magnitude (peak to baseline) and pulse durations up to one nanosecond. For an example of how you can control and use pulse contrast with different laser settings, we invite you to read the recent paper by Peter Kazansky (University of Southampton, UK) on ultrafast laser writing in silica glass.

For the first time, a distinct application of polarization singularities in #laser #microprocessing demonstrated! "Polarization singularities provide a unique ability to dynamically shape vector beams using the design of geometric phase elements (GPEs) proposed in this work and based on hollow center space variant #waveplates.  ... The produced GPEs were successfully used to generate high-energy polarization singularities and these were employed in #glasswelding, #thinfilm removal, and #silicon #ablation applications.  The experimental results demonstrate the significant impact of the shape of the beam on the material processing results.  Polarization singularities with tunable #FlatTop beam profiles offer enhanced control over heat deposition and material modification, enabling the production of more precise and uniform structures compared to Gaussian beams. These findings underscore the potential of flat-top beams in various material processing applications, including #volume #modification of transparent materials and selective #surface #ablation of thin metallic films, as well as for #semiconductors." The article - Polarization singularities for shaping of vector flat-top beams in utilization for high-power laser micromachining of various materials - was published in Optics & Laser Technology, Volume 177, 2024.

Metal lattice structures produced by means of additive techniques are attracting increasing attention thanks to the high structural efficiency they can offer . The present work aims to describe and validate a FE modelling technique simulating the behaviour of lattice structures under bending load conditions. The FEM validation was performed by three-point bending test on flat specimens produced in Ti6Al4V by using #ElectronBeamPowderBedFusion (EB-PBF) technology.

When precision meets the future of engineering.   A few months ago, we achieved a groundbreaking milestone with the commissioning of our third-generation Electron Beam welding machine. This cutting-edge technology offers unparalleled advantages, ensuring precision and quality in every weld. With minimal heat-affected zones and deep penetration, Electron Beam welding allows for strong, seamless joints even in complex geometries, minimizing distortion and maintaining structural integrity.    But it doesn't stop there. Encardio Rite sets the industry standard for durability with sensors boasting an impressive IP68 rating, guaranteeing protection against dust and water ingress. By utilizing Electron Beam welding to hermetically seal our sensors, we ensure accuracy and longevity in monitoring structures in extreme climates and safeguarding critical infrastructure.    Innovation knows no bounds at Encardio Rite.    #precisionengineering #ElectronBeamwelding #durability #EncardioRite
