As laser processing becomes more accessible to makers, small workshops, and industrial users, many beginners are searching for a clear, reliable guide on how different laser machines work — and which one to choose.
This Argus Laser Beginner’s Guide explains the fundamentals of CO₂ lasers, fiber lasers, and diode lasers, helping you select the right equipment for your business or creative projects.

1. How Do Laser Machines Work? (Simple Explanation)

Although different laser types use different technologies, the basic principle is similar:
A laser machine generates a concentrated beam of light that delivers energy to a specific point. This energy heats, melts, or vaporizes the material to create clean cuts, engravings, or markings.

Different laser sources create different wavelengths, and wavelength determines what material the laser can process.
Understanding this helps you choose the right machine without wasting money.

2. What Is a CO₂ Laser?

CO₂ Laser = Gas Laser (10,600 nm wavelength)

CO₂ lasers use a mixture of carbon dioxide gas excited by electrical energy to generate a strong infrared beam.

Best for:

• Wood

• Acrylic

• MDF

• Leather

• Paper

• Fabric

• Rubber

• Glass (surface marking)

• Non-metal materials in general

Why choose CO₂ lasers:

✓ Smooth edges, high precision

✓ Affordable and beginner-friendly

✓ Perfect for DIY studios, small businesses, craft shops

3. What Is a Fiber Laser?

Fiber Laser = Solid-State Laser (1064 nm wavelength)
Fiber lasers use a fiber-optic cable doped with rare-earth elements to generate a high-energy beam.

Best for:

• Stainless steel

• Aluminum

• Brass

• Copper

• Titanium

• Industrial metal engraving and cutting

Why choose fiber lasers:
✓ Very high speed
✓ No consumables
✓ Ultra-fine engraving
✓ Industrial-grade durability

Ideal for customers needing metal marking, metal cutting, tools engraving, serial numbers, barcodes, etc.

4. What Is a Diode Laser?

Diode Laser = Semiconductor Laser
Diode lasers are compact and energy-efficient, commonly used in small desktop machines.

Best for:

• Light wood engraving

• Cardboard

• Leather

• Basic hobby projects

Why choose diode lasers:
✓ Very low cost
✓ Small and portable
✓ Simple hobby engraving

Limitations:
✗ Low power
✗ Cannot cut thick materials
✗ Poor performance on glass or acrylic
✗ Not suitable for metals

5. CO₂ vs Fiber vs Diode: Which One Should You Choose?

If you’re just starting and plan to work with non-metal materials, a CO₂ laser is the best choice.
If your work involves metal, a fiber laser is essential.
If you only need small hobby engraving, a diode laser is enough — but results are limited.
