10 Brilliant Laser Applications

Laser engraving stone slate

How many times do your friends use the Doctor Evil voice when talking about “lasers”? It seems you can’t bring it up without someone relating it to Austin Power’s movie quotes. While Dr. Evil had evil intentions for his laser technology, it has practical and functional uses in the real world, here on Earth.

The following will discuss 10 not-so-evil laser applications.



Wood engraving is a centuries-old craft. It was performed by highly-skilled craftsmen and hand tools. Today, anyone with a little tech knowledge can engrave beautiful crafts using a laser system.


Plastic is a most common laser engraving application. Words, names, numbers, barcodes, and other such text are imprinted on plastic.

Crystal & Glass

Glass etching used to require a sandblaster and a craftsman with a steady hand and mad skills. Nowadays, instead of being a manual process, you can program your laser machine to etch on glass or crystal without all that work. Not only is this process more efficient and precise today, it’s more cost-effective.


Gold, while one of the most precious and valuable of metals is hard to work with because of its malleability. Experienced jewelers that regularly engrave on gold take many precautions to avoid damaging the gold and decreasing its value. Laser technology allows them to perform this task with the highest precision and accuracy while keeping material loss down to a minimum.


Aluminum is another popular material used for laser engraving. Jewelry, smartphone cases, and mementos made from aluminum can be engraved using laser systems. That’s where all those intricate designs and details come from on phone cases and covers.

Slate & Stone

Chisels and hammers were used to engrave on stone and slabs of rock way back in the day. Sometimes, the stone craftsmen had to start over with another slab because the rock cracked. Laser technology took these problems out of the engraving process. Modern laser systems can be programed to engrave on various types of slate and stone.

Anodized Metal

Anodized metal is a very hard surface upon which to etch. It’s designed to resist mechanical force and corrosion through treatments to make it durable and long-lasting. Laser technology can be programed to etch on this tough metal without compromising its traits that make it so durable.


Metal is a dense substance that requires more force to engrave. However, you can’t tell the difference between what is engraved on a dense plastic and metal items. Names, barcodes, words, and other text are engraved on metal just like plastic, only at a higher power level.

Engineering and Tools

Engraving on engineering instruments and tools must be precise and accurate. Their very purpose for measuring and precision dictates that fact. Laser engraving is the most accurate and precise method for engraving on tools without affecting the implement’s integrity.

Electronic Components

Computer motherboards and chips are beyond fragile components. Just a miniscule scratch will affect whether these components work or not. A tiny mistake renders these components useless. The refined process of laser technology etches on electronic components of all types with exact accuracy and precision without compromising the component.
