CO2, vanadate and fiber lasers Common laser types available in the market The laser machines available in the market mainly differ by the laser source they use. We mainly talk about CO2 lasers, fiber lasers and vanadate lasers. Each laser type has its own advantages and disadvantages and is suited ...

Common laser types include "sealed-off" gas lasers (CO2 lasers) and fiber lasers. Both operate economically and feature a long service life. CO2 lasers are especially suited for laser engraving and laser cutting. Fiber lasers are mainly used for laser marking. In addition, with the Speedy...

Laser light can be highly collimated by means of a focus lens. An extremely high energy density is generated in the focus of the laser beam, which can be used for melting or evaporating the material. In addition, using suitable optics (mirrors), laser light can be directed and reflected, and this c...

"LASER" stands for "Light Amplification by Stimulated Emission of Radiation". Lasers amplify light by absorbing and radiating energy. The laser radiation is generated by a laser source. For this, concentrated energy is supplied to a crystal rod (solid state laser) or a special g...

There nothing like housing your modern technology in the fade of old technology. This is a small laser cut box that can hold up to 8 full-sized SD flash cards. There is a small living spring that will hold the lid shut when it bouncing around in your bag. You can open the box from either side. With ...

You need focussing optics and really good cooling of the diode!

Combining more diodes optically is possible, but you need really good optics and complex adjusting systems, what's not worth the fuzz ... better buy stronger fibercoupled diodes ...

Hi Mcmorran, as bicycle rubber is black and so very good absorpting, you can cut it with a 'weak' pigtailed diode-laser of maybe 1 Watt and a single focussing lens - higher powers and/or a CO2-laser will do better and much faster. But you have to filter and exhaust the smoke, as it's corrosive and h...

When I first started taking my digital fabrication class, my teacher showed us an example of a ring he had cut on a laser printer. I really liked the design of the ring, but it required four separate pieces of acrylic to form the base of the ring and a fifth peice cut in an s that would fit in the t...

This is my version of the 8 bit violin. A lot of things have changed since I stubbornly wanted to do it my way. One of those things is that I wanted those nice chequered press-fit sides. This adds a nice purfing-like trim (struggled to make it really press-fit actually). The top has a slight curve i...
