Different types of lasers are needed for different applications. Based on their gain medium, lasers are classified into five main types: gas lasers, solid-state lasers, fiber lasers, liquid lasers (dye lasers), and semiconductor lasers (laser diodes).
All over the world, laser products are identified with warning labels like the ones above. But what does a Class 1 label mean? And who decides which labels to apply?
Every capital investment is a huge decision, and buying a laser marking machine is no exception. Despite the high initial cost, the investment is worth every penny for a growing number of manufacturers.
For a lot of people, lasers are small boxes that shoot red dots, which drive cats crazy. But in fact, laser systems are used in many manufacturing processes.
Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.
If you are relatively new to laser technology, you are probably wondering what’s the difference between laser engraving and laser etching. And more importantly, which one is right for you.
The most common methods for e-coating removal include burn-off ovens, sandblasting, and chemical stripping. A more modern technology is laser cleaning. It is adopted by manufacturers who need speed and precision, as well as those who want to get rid of consumables.
Laser dust removal is the process of removing dust from a surface using laser ablation. Any types of dusts produced in work environments can be removed, such as metallic, plastic and organic dust. As the laser beam irradiates the surface, burnt off dust is vaporized and extracted using a dust extraction nozzle
Deep laser engraving is a process that uses a highly focused beam of light to engrave 3D forms into metals. Pulsed fiber lasers are the best tools for deep engraving because they reach the high peak power needed to carve metal surfaces.
If you’ve ever stripped the phosphate coating off a part, or managed a phosphate conversion coating process, chances are you’ve seen your fair share of chemicals. If you want to get rid of chemicals during phosphate coating removal, laser cleaning may be the solution you’re looking for.
Fiber lasers are everywhere in the modern world. Due to the different wavelengths they can generate, they are widely used in industrial environments to perform cutting, marking, welding, cleaning, texturing, drilling and a lot more.
To make sure laser technology is perfectly safe in manufacturing environments, it must be implemented properly to prevent health risks. One of the important laser safety considerations is the extraction and the filtration of fumes.
