Laser Diode vs CO2 Laser Cutting/Engraving Systems Comparison

Basics

• This page aims to compare Laser Diode and CO2 Laser based Laser Cutters and/or Laser Engravers

Laser Diode

Advantages

• No mirrors required, only the diode, and lenses on that axis
• No Seperate Laser Tube Needed
• CAN be cheaper

Disadvantages

• Seem to be sold anywhere from 1-10w no more than that
• So they can only do engraving, and some of the higher up wattage, and the 10w laser can cut some materials (wood, acrylic)

CO2 Laser

Advantages

• 40 watt is usually the lowest power offered, and thus is far more capable than diode systems
• Usually has a large bed more comprable to a CNC Router

Disadvantages

• Usually needs a watercooler for the tube
• Has a glass laser tube (fragile)
• Has a larger bed (great for larger projects, but takes up more space)
