Know what your laser is actually doing to the material.
Laser Ledger turns your source specs and LightBurn settings into real physics — energy deposition, pulse-overlap heatmaps, and peak surface temperature — so you can dial in settings with understanding instead of guesswork.
Energy per unit area
Areal dose (J/cm²), per-pulse fluence, peak power and peak irradiance — the numbers that actually determine your result.
Pulse-overlap heatmap
See exactly how pulses stack up: heavy mottling at low speed, clean dots or gaps at high speed. Slow vs. fast made visible.
Peak surface temperature
A moving-Gaussian thermal model predicts how hot the surface gets and whether you'll anneal, melt, or vaporize the material.
Both laser families
Pulsed fiber / MOPA galvo lasers and continuous-wave diode / CO₂ machines, each with the right physics.
Real machine presets
Start from curated specs for common hobbyist lasers — OMTech, xTool, Gweike and more — then tweak any parameter to match your unit.
Marking-regime read-out
Instant classification against the material's anneal, melt and vaporization thresholds so you know which process you're in.
Pick your laser
Choose from curated machine presets, or enter your own source parameters.
Enter LightBurn settings
Power, speed, frequency, Q-pulse, line interval — the knobs you already use.
