How High-Power UV - Femtosecond and Picosecond Lasers Assist In Precision Micromachining

Image
The foundation of our industrialized society depends on technological advancement. For a manufacturer, producing a tangible product has often meant shaping, modifying, and joining different materials. That means creating more complex products, utilizing fewer resources, and becoming more cost-effective, year after year. Production processes have now had to switch from conventional machining to modern high-power UV laser micromachining. Industries such as energy, transportation, and consumer electronics need better pricing for ever-increasing features. Medical devices benefit from improved miniaturization but must also meet rigorous limits on biocompatibility. Products for these industries need continued improvement in size and cost reduction while at the same time improving capabilities. Femtosecond and picosecond laser micromachining has, in large part, enabled this achievement, especially in markets with acute sensitivity to scale or constraints. Advantages of high-powered UV las...

Why Femtosecond Laser Micromachining Is A Preferred Choice Over Other Micromachining Methods

  Femtosecond laser solutions, which include micromachining, are constantly growing and evolving across various business areas. Ultrafast lasers are predominantly used in applications where the requisite HAZ and efficiency are not achieved by traditional CW, long-pulsed fiber, nanosecond, and picosecond laser systems. A  femtosecond laser represents  10 to the −15 of a second, which is one-millionth of a billionth of a second. At given pulse energy, the laser's peak power increases as the pulse's length become shorter. Hence, femtosecond lasers have a much higher peak power than longer pulsed picoseconds, millisecond or nanosecond pulsed lasers. Since total energy is transmitted to the substance and less is drawn into heating the material, these higher peak powers result in higher removal rates in a material. These femtosecond lasers' high peak power, sometimes several-MW, disrupts the atoms and electrons in the material, resulting in what is known as a "Coulomb explos...

Why High-Powered Laser Micromachining Is The Perfect Choice For Laser Cutting Projects

Image
Ever since its invention, the value of lasers has evolved by leaps and bounds. Lasers can not only cut and micromachine quickly, but they can do so at a low cost with accuracy and speed efficiency. Laser micromachining has replaced numerous other types of cutting methods that were available before their invention, and with the increase in the number of laser cutting projects, their demand has been increasing every year. Laser micromachining methods are flexible and from fragile materials such as cloth, plastic, and paper to other more robust materials such like wood, metal, and stainless steel, practically anything can be cut or micromachined using a laser. Perhaps best of all, most of the laser cutting projects using high-quality, precision laser cutting systems take no time & involve minimal human intervention. The various benefits offered by laser micromachining methods have led to their use in different laser cutting projects. Several such advantages include a reduction in...
