Laser types

Diode vs CO₂ vs fibre, MOPA, infrared and UV

Laser source and wavelength influence what energy a material absorbs. Wattage alone cannot tell you what a machine is suitable for.

Evidence key: Sourced fact linked evidence; Research-only analysis our interpretation; Method or boundary how to use the information. Source links checked: 14 September 2026.
Research-only analysis The following profiles are task-routing summaries derived from documented technology characteristics. They are not measured performance, price or product recommendations.

Blue diode

Investigate for wood, card, leather and selected dark or opaque materials. Open-frame configurations add enclosure and installation questions that must be resolved separately.

CO₂

Investigate for cutting and engraving many organic materials and acrylic, including clear acrylic. Confirm extraction, cooling arrangements, maintenance and the complete installed footprint.

Fibre and MOPA fibre

Investigate for marking and engraving metals and selected engineering plastics. Confirm the marked field and lens for the product. MOPA pulse-control flexibility does not turn a marking system into a general sheet-material cutter.

Infrared modules

Compact machines may use an infrared source for selected metals and plastics, sometimes alongside a diode. Output, wavelength and intended depth must be checked for the exact module.

UV

Investigate for fine marking of selected plastics, glass, crystal and electronic components. Confirm the exact material, intended result and marked field. “Cold marking” must not be read as fume-, fire-, skin- or eye-safe.

Sourced fact IEC 60825-1 is the international product-safety standard used to classify laser products by accessible laser radiation. See IEC 60825-1 overview.
Research-only analysis Future machine records will model each laser source independently because a single enclosure may contain two sources or accept interchangeable modules.

Technology is only one layer

After source suitability, compare the complete machine: enclosure, accessible hazard in each mode, work area, Z clearance, positioning, extraction, cooling, software, parts, support and ownership cost.
