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.
