Overview
NEWLIFE Laser Diode Heat Sinks provide high-efficiency thermal management for continuous-wave (CW) and pulsed laser systems. Engineered from W–Cu alloys or high-purity copper, these heat sinks minimize thermal deformation while maintaining precise optical alignment in LD, VCSEL, and optical communication modules.
Produced via Powder Metallurgy (PM), infiltration, and precision CNC machining, NEWLIFE laser diode heat sinks achieve complex microcavities, stepped surfaces, and integrated mounting geometries that are difficult or cost-prohibitive to produce with traditional machining or extrusion. NEWLIFE's self-developed powders ensure uniform density, predictable thermal expansion, and high mechanical stability even under rapid thermal cycling, providing reliable performance in industrial, medical, and high-power optical systems.
Compared with conventional machined copper or aluminum solutions, PM-based W–Cu heat sinks offer higher thermal conductivity, better dimensional stability, and near-net-shape capability, reducing post-processing and material waste while enhancing design freedom.
Applications
