Continuous laser system YLR-AM

fibernear-infraredfor materials processing

Overview
Dual-mode fiber lasers integrate single-mode and multi-mode outputs within a single fiber to enable rapid switching between small and large spot sizes. Designed for high-throughput metal additive manufacturing, sintering and welding applications, these lasers provide configurable power distribution and on-the-fly beam shaping for process flexibility and throughput improvement.

Key features

• Single-mode and multi-mode output from one fiber — two spot sizes without external moving optics
• Adjustable mode technology enabling near-instant optical switching between spot sizes (<50 µs)
• Suitable for high-speed 3D metal printing, copper processing and industrial welding
• Independent control of power and fluence for each spot
• Reduced sensitivity to alignment, vibration and contamination due to absence of precision moving optics

Typical fiber / beam options

• Single-mode fiber core diameter: 14 μm
• Multi-mode fiber core diameter: 40 μm
• Beam quality (single-mode): M² ≈ 1.3
• Multi-mode BPP: < 2.4 mm·mrad

Adjustable Mode Technology
On-the-fly switching between spot sizes (<50 µs) enables sequential processing of fine and coarse features without mechanical beam-size changes. The technology delivers repeatable switching, independent adjustment of each output's power and fluence, and stable performance in production environments.

Two Spot Sizes. One Laser.
The integrated dual-mode concept eliminates slow external bulk optics for spot changes, enabling near-constant fluence switching for higher throughput in additive manufacturing and welding workflows.
