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...

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...

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 (...

Plastic panel UV laser lettering has little effect, no deformation or scorching
May 17 , 2021
UV laser marking plastics, white\black\graphics and texts can be marked, and the marking is clear Lasers are roughly classified into fiber lasers, carbon dioxide lasers, and ultraviolet lasers. Some plastics are easy to mark because they absorb laser light, while some plastics do not absorb laser light and cannot be marked with laser light at all. The absorption rate of the laser is ...
