Laser Marking for Glass / Paper / Ceramics Other Materials
Apr 28 , 2021
Understanding the various laser types and wavelengths makes marking possible on a variety of materials. However, unless the optimal laser marker for the material being used is selected, achieving the desired finish will not be possible. This section introduces how to select the optimal laser marker for glass, paper, ceramics, PCBs, and other materials. Glass Paper Ceramic Printed Circuit Bo...

UV Laser Marking for 2D Codes (Data matrix / QR Code / Barcode
Apr 28 , 2021
While demands for smaller and thinner products and more detailed traceability continue to grow, there are increasing needs for packing more information within a limited space on manufactured products. A 2D code can hold tens to hundreds of times the information of a barcode. This high information density allows a 2D code to hold the same amount of information as a barcode in as little as 1/3...

Non-contact marking of plastic materials with 355nm UV laser
Apr 30 , 2021
Non-contact marking of plastic materials with 355nm UV laser New Era Securities analysis pointed out that the current national helmet penetration rate is extremely low. It is conservatively estimated that the production and sales of helmets will not exceed 50 million yuan per year. The demand for new helmets may exceed 300 million. If the average price is 100 yuan per piece, it corresponds ...

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...

DPSS vs. Fiber Lasers
May 10 , 2021
DPSS vs. Fiber Lasers Fiber lasers are compact, rugged, reliable, & reasonably priced. So, why choose DPSS over fiber? DPSS lasers provide the same benefits fiber lasers offer, plus a host of additional benefits, allowing the versatility, precision, and quality you need for a vast range of applications. The DPSS lasers from Bright Solutions boast a rugged, fixed laser cavity design, resulting ...

ADVANTAGES OF TWO-PHOTON MICROSCOPY UTILIZING FEMTOSECOND FIBER LASERS
May 11 , 2021
ADVANTAGES OF TWO-PHOTON MICROSCOPY UTILIZING FEMTOSECOND FIBER LASERS Microscope Traditional microscopy is the technical field of using microscopes to view objects and areas (mostly cells) that are not within the resolution range of the naked eye. Compound microscope designs feature objectives and condensers, but also consists of very simple, single-lens instruments that are often hand-hel...

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 (...
