  • Ekspla Atlantic 6 Compact Air-cooled Industrial Picosecond Laser

    Ekspla Atlantic 6 Compact Air-cooled Industrial Picosecond Laser

    Ekspla's  Atlantic 6 is designed for industrial micromachining applications as a reliable, compact and cost effective solution. Hybrid fiber and DPSS technologies implemented in this model make it also very energetically efficient, which enables air cooling solution for laser head. No water is used inside laser, which means you should not worry about unexpected leakage, regular water replacement or possible chiller failure. Laser head generates only around 150 W of heat, so it required quite simple heat management solutions for system integrators. Laser do not require a chiller or big heat exchanger, so all control and power supply electronics is fit into standard 3U 19-inch rack.

    Hybrid technology enables new pulse control features, which are not present in earlier Atlantic series lasers. Atlantic 6 can provide burst of pulses spaced only 25 ns in time, so called seeder burst mode. It is very useful in material processing applications, because in some cases it allows to increase process efficiency or at least provides additional variable parameter for process optimization. Atlantic 6 has broad range of accessible pulse repetition ranges, from single pulse to 1 MHz. Read more.

    Ekspla: New and Promising Applications in Laser Materials Processing

    Ekspla lasers are being used in developing new and promising applications in Materials Processing. Techniques including Laser-assisted Selective Copper Deposition on Polymers and Laser Photopolymerisation are finding rapid niche growth. Ekspla has recently added ten new short articles outlining new applications for Laser Materials Processing here. It is part of the Ekspla Applications article library

    Laser-assisted Selective Copper Deposition on Polymers

    Fabrication of circuit traces is the most challenging task in Moulded interconnect devices (MID) production, being both technically difficult to achieve and difficult to make cost effectively. Moulded interconnect devices (MID) – an injection-moulded thermoplastic part with integrated electronics – offer material, weight and cost savings by integrating electronic circuits directly into polymeric components. Selective Surface Activation Induced by Laser (SSAIL) is a new technology for writing electronic circuits directly onto the dielectric material. This is done by modifying the surface properties with a picosecond pulse laser and has been developed at the Center for physical sciences and technology. Picosecond lasers can write the circuits directly by modifying the surface of polymers followed by an electroless metal plating. SSAIL is a three-step process. First is surface modification by laser; second is chemical activation of the modified areas; and the last step is metal deposition by electroless plating. The new technology offers laser writing speeds of up to 4m/s, and therefore spatial plating pitch is kept narrow at 25 µm.

    Photopolymerization is a powerful and versatile light-activated resin solidification process. It is attractive for the fabrication of complex micrometer-size three-dimensional (3D) structures by employing nanosecond as well as picosecond lasers. Many fabrication techniques of polymeric microstructures are based on photopolymerization via photolithography, digital light processing lithography, rapid prototyping, multi-photon polymerization, 3D printing, interference lithography, etc. Polymeric microstructures with a prescribed shape and thickness are desirable for a wide range of applications: tissue engineering, electronics and optics, coating, adhesives, drug delivery, microfluidics and surface science.

    Bio-inspired Shark-skin-like Surface Structuring

    Bio-inspired surfaces decrease friction with gases and the most recognizable textures are shark-skin-like riblets. Such surfaces can be formed using  direct laser ablation with high flexibility options. The bio-inspired riblet surfaces were formed using picosecond ultraviolet laser ablation on pre-heated Teflon at various sample temperatures. The ablation of hot Teflon was found to be 30% more efficient than the conventional laser structuring at room temperature. The functional properties and surface morphologies of the laser-fabricated textures were found to be close to the simplified geometry of shark-skin. The friction of structured Teflon surfaces with the flowing air was investigated using a drag measurement setup.
