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...

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...

uv or green laser Etching on Glass
May 12 , 2021
How deep will the laser etch into glass? With a laser you can create a very light etch. This is not sandblasting and you won't achieve that depth, but you can quickly create very elaborate designs with a laser that is lightly etched into the glass. It's a unique look that many people prefer to sandblasting. Do I have to mask the glass before engraving? Unlike sandblasting, wit...
