Violet 405nm 5W Space Coupling Fiber Laser Module
The space coupling fiber laser module is a light source device that is calibrated through an optical lens group, combined to increase power, and then coupled to an optical fiber.
The Violet 405nm 5W Space Coupling Fiber Laser Module—a high-power, near-UV light source engineered for precision industrial applications requiring flexible beam delivery and exceptional stability. Leveraging advanced space coupling technology, this module delivers 5W CW output through a multimode fiber, enabling precise energy deposition for photolithography, material processing, and bio-photonics applications.
Core Advantages for Precision Processing
1. Near-UV 405nm Wavelength: Unmatched Photonic Precision
- 405nm ±5nm wavelength: Delivers near-UV performance with high photon energy (3.06eV) for efficient photopolymerization, photoresist exposure, and fluorescence excitation
- Superior absorption: Optimized for materials sensitive to near-UV light, including polymers, photoresists, and biological samples—ideal for microfabrication requiring sub-micron resolution
- Low thermal impact: Minimizes heat-affected zones (HAZ) compared to longer wavelengths, preserving material integrity in delicate processing applications
2. Space Coupling Technology: Flexible & Efficient Beam Delivery
- Advanced free-space coupling design: Achieves >85% coupling efficiency with 105µm/125µm multimode fibers, maximizing power transfer while maintaining beam quality
- Modular fiber interface: Enables quick fiber swapping for different applications, with standard fiber lengths of 1m/2m (custom lengths available up to 10m). The standard module is without fiber, if you need the fiber, please contact our sales person.
- Beam uniformity: Delivers consistent energy distribution across the fiber core, ensuring uniform processing results for large-area exposure applications
3. 5W High-Power Output: Industrial-Scale Productivity
- 5W CW output power: Provides sufficient energy for high-throughput processing, reducing cycle times by 30% vs. lower-power alternatives.
