Precision Beam Delivery, Flexible Integration – ND:YAG Laser Articulated Arm

Shengdayu's ND:YAG laser articulated arm, designed for common ND:YAG wavelengths including 1064 nm and 532 nm, delivers efficient and stable beam transmission solutions across industrial, medical, and research applications through high-reflectivity optics, superior damage resistance, and a flexible seven‑joint architecture.

Optical Performance: >99.5% Reflectivity, 20 J/cm² Damage Threshold – Engineered for High‑Energy Pulse Transmission

At the heart of every articulated arm are its optics. Shengdayu's ND:YAG articulated arm is equipped with premium reflective mirrors, precision‑coated for ND:YAG laser characteristics, delivering reflectivity consistently above 99.5% and a damage threshold of 20 J/cm². Together, these specifications translate into tangible performance benefits in real‑world operation:

Minimal transmission loss: Laser energy travels through the seven‑joint path with negligible attenuation, preserving output power for consistent, stable performance in cutting, welding, marking, and aesthetic procedures.

Exceptional damage resistance: The 20 J/cm² damage threshold provides outstanding resilience against high‑energy pulsed lasers – a 4× improvement over the industry‑standard 5 J/cm². It reliably withstands prolonged exposure to high‑energy density pulses, effectively preventing mirror "burn‑in" or coating delamination, and significantly extending service life of the critical optical components.

Greater safety margin: The high damage threshold delivers ample headroom for operational variability. Even under laser energy fluctuations or pulse instabilities, the optics remain well within safe operating limits – reducing unplanned downtime and lowering maintenance costs.

Superior thermal stability: High reflectivity minimizes optical absorption, and combined with the high damage threshold design, it substantially reduces thermal drift – ensuring reliable operation even under extended, high‑duty‑cycle runs.

Mechanical Design: 7‑Axis Articulation for Full‑Range Positioning

Flexibility is key to adapting the arm to complex workspaces. The seven‑joint balanced design delivers a full 360° range of motion with smooth articulation. Compared to six‑joint alternatives, the seven‑joint configuration offers greater dexterity, effortlessly accommodating multi‑angle aesthetic treatments, intricate industrial beam routing, or flexible laboratory setups – with intuitive handling and enhanced maneuverability.

For balancing, customers can choose between torsion‑spring or counterweight systems, both ensuring stable suspension at any angle – reducing operator fatigue and improving precision in every application.
