Laser Engraving

Laser technology has developed quite impressively in recent times and has been harnessed to enhance music production (CD), perform precision surgery and much more. Initially, these were the main ways that laser technology was used for since research as to its full uses and implications was still ongoing. As more research is conducted, more uses of laser technology are being unearthed. One recent discovery is that laser technology can be used to engrave objects. No doubt we live in a consumer world where millions of products exist in the marketplace. These come in all shapes, sizes and containers and in the past, it would be easier to just print labels on these products and slap them on the container. But innovations in laser technology have changed all that and products can be directly engraved using laser.

Laser engraving has radically changed the way products are embossed. This essentially changes the way we mark the surface of objects. This technique has some limitations namely those imposed by the fact that the technology tends to be complex because it involves heavy computer and software use which requires specialized training. But multiple companies have adapted the practice and can now very precise and clean engravings at record speeds.

One advantage of using laser engraving is that no cumbersome mechanical tools are required. For years these had become the acceptable way of engraving products and were dangerous and expensive because of wear and tear. The machine heads had also to be replaced regularly.

Laser engraving has recently escalated especially when it comes to specialized products which are categorized as "laserable". Such materials include but are not confined to some metal allows and polymer-made products
Sometimes, it is not possible to employ laser engraving on a product because its surface is not conducive or if its condition does not support that. In that scenario there is an alternative termed as "marking". Marking covers a broad range of procedures performed on surfaces such as printing and branding but laser technology has also recently come to bear on marking. This is known as laser bonding..

We mentioned earlier that laser engraving technology can be highly technical and complex and involves machines that work in various parts and components to generate the laser. There are essentially two to three parts to the equipment namely the laser itself and the controller. Then off course there is the surface being engraved. The laser itself is a thin pencil-like beam that emitted from the equipment and which then traces patterns onto the projected surface. The controller on the other hand is usually a computer with installed software that manages and issues controls the direction, speed, intensity, and width of the laser beam. The computer is also able to sense and adjust the laser to accommodate the type of surface being worked on.

Laser engraving has resulted in very innovative ways of engraving surfaces which in ordinary circumstances would be hard to engrave, for example glass. Since the laser beam is very flexible and agile, there is virtually no limit to the designs that can be engraved on a surface.

How powerful does a laser diode have to be to engrave metal?

How powerful does a laser diode have to be to engrave metal? What kind of milliwatt, and wavelength would the diode have to be to be able to engrave metal?

A 30W laser should be able to engrave metal, usually these diodes are only made in 808nm wavelenght.
