Aerospace industry moving to laser marking
May 07 , 2021
More than a half-century since the dawn of the Jet Age, the aerospace industry finds itself once again leading the way into the future. Because of the need for both reliability and traceability, aviation manufacturers are driving a shift from dot-peen marking to laser marking. And this shift will soon reach jet-like speed as government regulators come around to the new methods and app...

Laser Marking on Plastic
May 08 , 2021
‘Plastics’ refer to materials with widely differing chemical compositions, which in turn means differing outcomes for the processes applied to them, including laser marking. Indeed, among plastics we can distinguish between polycarbonate, polyamide, polyester, PE, PET, ABS, and many others. These influence the choice of laser in terms of required wavelength. By way of example, P...

355nm UV laser thermally affected small marking plastic air switch without deformation
May 10 , 2021
355nm UV laser thermally affected small marking plastic air switch without deformation Although air switches are widely present in everyone's homes, few people know something about this little thing that guarantees the safety of our families. Even if they do, only high school students may know something from physics textbooks. Because the air switch has a long life cycle and almost n...

Why Laser Damage Testing is Critical for UV Laser Applications
May 10 , 2021
UV Lasers There are numerous advantages to using UV lasers as opposed to longer wavelengths such as infrared or visible light. In materials processing, infrared or visible lasers melt or vaporize material, which can hinder the creation of small, precise features and damage the structural integrity of the substrate. On the other hand, UV lasers process materials by directly breaking the atomic bond...

BLUE DIODE LASERS ENABLE HIGH-QUALITY NON-FERROUS METAL WELDING
May 10 , 2021
Blue diode lasers have recently become known as an excellent tool for certain processing techniques regarding copper and other non-ferrous and highly reflective metals. Copper, gold, aluminum, and certain other metals absorb blue wavelengths more easily than any other wavelengths of visible or invisible light. This higher rate of absorption allows for both higher quality results and faster process...

UV laser marking watch glass, not easy to break and high-definition
May 11 , 2021
UV laser marking watch glass, not easy to break and high-definition Because glass is fragile and very hard, it always challenges the limits of traditional manufacturing processes such as milling, drilling, and grinding. The processing of sapphire glass mirrors is complicated, and it requires not only experienced craftsman skills but also high-end equipment to produce high-quality products. ...

LASER DIODE FUNDAMENTALS: WHAT ARE LONGITUDINAL MODES?
May 11 , 2021
LASER DIODE FUNDAMENTALS: WHAT ARE LONGITUDINAL MODES? Laser diodes must meet two critical requirements to facilitate the lasing process. The first requires that, at a minimum, the laser cavity's gain increases to the point that it reaches unity with the level of losses. This unity state is known as the gain threshold. If you missed it, read our previous blog, titled "Laser Diode Fundamentals: Dio...

WHY IS A LOW JITTER FEATURE IMPORTANT IN ACTIVELY Q-SWITCHED DPSS LASERS?
May 13 , 2021
WHY IS A LOW JITTER FEATURE IMPORTANT IN ACTIVELY Q-SWITCHED DPSS LASERS? In actively Q-switched lasers, the user controls the pulsed laser output, so that no laser pulse emission occurs without providing a proper input signal, aka "the trigger". Due to the trigger signal propagation through the interface electronics, the Q-switch driver chain, and the laser resonator build-up time, a time delay (...
