Laser Marking Parameters Guide: How to Adjust Power, Speed, and Frequency
Laser marking quality directly depends on the correct adjustment of the parameters used. Power (W), speed (mm/s), frequency (kHz), hatch (fill spacing), and focus settings are the main factors that determine the contrast, depth, and readability of the marking. Parameter optimization varies depending on the application in fiber, CO₂, and UV laser systems. This guide technically explains industrial laser marking parameters and presents in detail how they should be optimized for different applications.
Laser Marking Parameters and Their Effects
Laser power (Watt)
Laser power determines the amount of energy transferred to the surface. Higher power provides deeper and more intense marking.
Marking speed (mm/s)
Lower speed provides greater energy transfer and increases contrast.
Frequency (kHz)
Frequency determines the laser pulse density and affects surface quality.
Hatch (fill spacing)
The hatch value determines fill density and affects contrast.
Focus setting
The correct focal point provides maximum energy density.
Number of passes
Depth can be increased by making multiple passes.
Parameters according to laser type
Parameter settings differ for fiber, CO₂, and UV lasers.
Effect of material type
Materials such as metal, plastic, and glass require different settings.
Heat management
Excessive heat may cause surface deformation.
Industrial application compatibility
- Mass production
- High precision
- Deep engraving
- Micro marking
How Is Parameter Optimization Done?
Metal marking
With fiber laser, the balance between power and speed must be adjusted correctly.
Plastic marking
Low heat impact is important in UV and CO₂ lasers.
Deep engraving
High power and low speed are used.
Surface marking
Low power and high speed are preferred.
DataMatrix marking
Parameters should be optimized for readability.
QR code marking

Inline production
The balance between speed and quality should be optimized.
Camera verification
Code quality should be checked with a camera.
Sample testing process
Parameters should be determined through testing.
