⚡ Quick Reference: Common Migrations
3kW → 6kW Fiber: Speed ≈ 1.7× | CO₂ → Fiber (metals): Power ≈ 0.65× | 20W → 50W Marking: Frequency ≈ 1.6×, Speed ≈ 2.5×
↳ Values are approximate starting points for same-material, same-thickness migration. See beam quality guide for M² impact details.
Transfer proven laser parameters between different machines with automatic power scaling, focus correction, speed adjustment, and gas pressure optimization. Supports both cutting and marking/engraving applications. For the engineering background behind each correction, see our Parameter Migration Guide.

Same material assumed — enter different thickness if needed
Select Cutting Migration for sheet/plate cutting parameter transfer, or Marking/Engraving Migration for laser marking, engraving, and surface treatment applications. Each mode uses different correction models optimized for the specific process physics.
Input your current (source) laser's proven parameters — the settings that produce good results on your existing machine. Include laser type, power, and process-specific parameters (speed, M², gas pressure for cutting; spot diameter, frequency, scan speed for marking). These are your baseline reference values.
Enter the target laser's specifications — type, power, and beam quality (M² for cutting) or spot diameter (for marking). The calculator uses these to compute the necessary corrections. You can also enter a different material thickness if your application changes.
Review the calculated parameters, correction factor breakdown, and recommendations. Use the migrated speed/frequency as a starting point, and perform test cuts/marks with ±10-15% variation to optimize for your specific equipment. Pay attention to warnings about edge cases (very high power ratios, wavelength changes, etc.).
Source: 3kW Fiber laser, M² = 1.2, 6mm carbon steel at 3000 mm/min, 12 bar N₂
Target: 6kW Fiber laser, M² = 1.15, same thickness
Result: Migrated speed ≈ 5040 mm/min (1.68× increase), Gas pressure ≈ 12 bar (unchanged), Focus factor ≈ 0.96× (slightly tighter focus due to better M²). The power doubles but speed increases only 1.68× due to diminishing returns at higher power (P^0.75 scaling).
Source: 4kW CO₂ laser, M² = 1.3, 10mm stainless steel at 1500 mm/min, 15 bar N₂
Target: 3kW Fiber laser, M² = 1.1, same thickness
Result: Migrated speed ≈ 2180 mm/min (1.45× faster despite lower total power). This is because fiber lasers have ~2.2× better metal absorption at 1070nm compared to CO₂ at 10.6μm. The wavelength correction factor (2.222) compensates for the power reduction (0.75×).
Source: 20W Fiber marking laser, spot 0.05mm, 50 kHz, 500 mm/s, 0.03mm spacing
Target: 50W Fiber marking laser, spot 0.05mm
Result: Migrated frequency ≈ 79 kHz (√2.5 scaling to maintain pulse energy), Speed ≈ 1250 mm/s (2.5× increase), Spacing ≈ 0.03mm (unchanged — same spot size). Higher frequency prevents excessive pulse energy that could damage sensitive materials.
Modern laser parameter migration combines empirical scaling laws with physics-based corrections. The non-linear relationship between power and cutting speed (P^0.75) reflects the thermodynamic reality that doubling laser power does not double cutting speed — a portion of additional energy is lost to increased heat-affected zone, wider kerf, and enhanced thermal conduction losses.
Speed: v_new = v_src × (P_tgt/P_src)^0.75 × (abs_tgt/abs_src) × (M²_src/M²_tgt)^0.5 × (t_src/t_tgt)^0.8
Focus Factor: f_factor = (M²_tgt/M²_src) × (λ_tgt/λ_src)
Gas Pressure: p_new = p_src × (t_tgt/t_src)^0.5
Sources: Steen & Mazumder “Laser Material Processing” (2010), ISO 11146-1:2021 beam characterization, manufacturer application data from IPG Photonics, Trumpf, and Bystronic.
Frequency: f_new = f_src × √(P_tgt/P_src × abs_tgt/abs_src)
Scan Speed: v_new = v_src × (P_tgt/P_src) × (abs_tgt/abs_src) × (D_src/D_tgt)
Line Spacing: s_new = s_src × (D_tgt/D_src)
Principle: Maintains constant line energy density (J/mm) and pulse overlap ratio to preserve marking quality across different systems.
2026 Industry Context: With modern fiber lasers achieving M² values below 1.1 and power levels up to 100kW+, parameter migration has become increasingly important as manufacturers upgrade their fleet. The correction models account for 2026-era beam delivery improvements, including advanced process fiber designs and adaptive optics, which allow tighter focus control and more predictable scaling behavior compared to earlier generation systems.
Parameter migration is necessary when upgrading to a higher-power laser, switching laser types (e.g., CO₂ to fiber), replacing equipment with a different brand/model, scaling production between prototype and production lasers, or transferring proven recipes from one facility to another. The calculator accounts for differences in power, beam quality (M²), wavelength absorption, and material thickness to produce optimized starting parameters for your target system.
Disclaimer: Migrated parameters are scientifically-based starting points, typically within ±15-20% of optimal. Always perform test cuts/marks on your target equipment before production use. Factors not captured include material batch variation, nozzle geometry, gas purity, ambient conditions, and machine-specific acceleration profiles.
