Raycus single-module fiber laser source
Raycus Single-Module Fiber Laser Source Introduction
 |
 |
Raycus single-mode continuous (CW) fiber lasers belong to the third-generation single-mode product line, covering power levels from hundreds of watts to tens of kilowatts (e.g., 2000W, 3000W, 6000W, 12000kW). The core technology is achieving fundamental mode Gaussian beam output, with a thinner fiber core and beam quality far superior to multimode lasers.
Product models include the RFL-C2000 (single-mode), RFL-C3000 (single-mode), RFL-C6000 (single-mode), and higher-power near-fundamental mode kilowatt models. The entire unit adopts a modular, air-cooled/water-cooled integrated design, suitable for industrial-grade 24-hour continuous operation, supports standard fiber output interfaces such as QBH, and can be directly integrated with robots and cutting/welding machine tools.
Raycus Single-Mode Continuous Fiber Laser Core Technology Features
 |
 |
1. Exceptional Beam Quality:Single-mode output with extremely low M² values (2000W model M² < 1.2; 3000W M² < 1.3; 6000W M² ≤ 1.5), resulting in a very small focused spot, high energy density, narrow kerf, and uniform weld penetration.
2. High Photoelectric Conversion Efficiency and Energy Saving:Electro-optical efficiency generally > 40%, significantly reducing industrial electricity costs; optimized thermal management also reduces cooling energy consumption.
3. Strong Resistance to High Reflectivity:For highly reflective materials such as copper, aluminum, and brass, a dedicated optical path design and monitoring algorithm are used to prevent backlight damage to the pump source and resonant cavity, achieving stable processing.
4. Long Lifespan + Maintenance-Free:All-fiber structure with no mechanical resonant components; pump source and gain fiber lifespan can reach tens of thousands of hours, allowing for long-term operation in industrial settings without disassembly or maintenance.
5. Flexible Control and Integration: Supports continuous/modulated dual modes with a wide modulation frequency range; provides RS232, EtherCAT, and other interfaces for easy integration into automated production lines; output fiber length is customizable (standard 20m).
6. Second-Generation Fiber Optic Transmission System: Optimized fiber coupling and transmission scheme reduces loss and ensures stability and accuracy during thick plate cutting/deep penetration welding.
