Chromatic Laser Processing Equipment for Stainless
Steel/Glass/Ceramic Materials
Chromatic laser processing equipment is a precision machining
system based on ultrashort pulse laser technology, achieving
micron-level precision in color marking, microstructure processing,
and functional surface treatment through selective interaction
between nanosecond/picosecond pulsed lasers and materials. The
system integrates tunable wavelength lasers (1064nm/532nm/355nm),
high-precision galvanometer systems, and real-time color monitoring
technology, enabling durable color pattern processing on stainless
steel, titanium alloys, glass, ceramics and other materials,
covering over 90% of the Pantone color gamut. Compared to
traditional anodizing or painting processes, it offers significant
advantages including consumable-free operation, non-contact
processing, and environmental friendliness, making it widely
applicable in high-value-added product surface treatments for
consumer electronics, jewelry, medical devices and other fields.
Chromatic Laser Processing Equipment Working Principles
1. Laser-Material Interaction Mechanism:
- Precise control of laser wavelength (355nm/532nm/1064nm) generates
plasmon resonance on material surfaces, forming 50-500nm thick
oxide interference films on metals for structural coloration
through thickness modulation.
- For non-metallic materials, laser-induced periodic surface
structures (LIPSS) create visual colors through light diffraction
and interference.
2. Core Subsystem Coordination:
- Optical System: MOPA fiber laser + acousto-optic Q-switching
enables independent control of pulse frequency (1-2000kHz) and
energy.
- Motion System: High-speed galvanometer (10m/s scan speed) +
precision linear motor stage (±2μm positioning repeatability).
- Color Control System: Online spectrometer monitors chromaticity
values in real-time, dynamically adjusting laser parameters
(power/frequency/scan spacing) via PID algorithm.
3. Process Flow:
- Material pretreatment → Laser parameter modeling → 3D path planning
→ Interference film growth → Color quality inspection →
Post-processing enhancement.

Chromatic Laser Processing Equipment FAQ
1. Q: What materials can be processed with chromatic laser marking
systems?
A: Chromatic lasers permanently mark stainless steel, titanium,
glass, and ceramics with Pantone-matched colors through nano-scale
oxide layer control.
