Laser 101: CO₂ vs. Fiber vs. UV — What's the Difference?

When you start exploring the world of laser machines, one of the first and most important questions is: What type of laser do I need? CO₂, fiber, and UV lasers all have their place, but each one is built for a different job. Choosing the right laser can save you time, money, and frustration down the line.

Here's a breakdown of the key differences to help you decide which one fits your needs best.

CO₂ Lasers — Versatile Workhorses

CO₂ lasers are some of the most commonly used machines in the engraving and cutting world. These gas-based lasers operate in the infrared spectrum and are excellent for working with organic materials.

Best for: Wood, acrylic, leather, paper, glass, rubber, and painted/coated metals (marking only)

Common Uses: Signage, custom gifts, home decor, tumblers, model making, prototyping

Rabbit Laser USA Models: SD and DL series ranging from 40W to 90W, with multiple bed sizes

Pros:

Affordable entry point
Versatile for cutting and engraving
Great for schools, hobbyists, and small businesses

Cons:

Cannot engrave bare metal directly
Requires more maintenance due to consumable laser tubes

Fiber Lasers — Metal Masters

Fiber lasers are solid-state machines that deliver high-power beams through fiber-optic cables. They're built specifically for engraving and marking metal, and can even cut thin-gauge metals depending on the wattage.

UV Lasers — Delicate Detailers

UV lasers use a short wavelength beam that produces a "cold mark" with minimal heat. They're primarily used in specialty industries that require ultra-fine detail without damaging the surface material.

At-a-Glance Comparison

Feature	CO₂ Laser	Fiber Laser	UV Laser
Price Range	$$	$$$	$$$$
Cutting Ability	Yes (non-metal)	Yes (thin metal)	No
Engraving Speed	Medium	Fast	Fast
Lifespan	2,000-10,000 hrs (tube)	~ 100,000 hrs	Varies, typically long

*Capable of cutting small gauge metal like thin stainless or aluminum sheet.

Which One is Right for You?

If you’re a maker working with wood, acrylic, or leather: CO₂ is your go-to.
If you’re engraving bare metal or cutting thin stainless: Fiber is your best bet.
If you're in electronics or medical manufacturing: UV might be what you need, though most makers and small businesses won't require it.
