Water‑Cooled High‑Power Copper Mirror
Reflective Parabolic Focusing Mirror & Applications
The parabolic focusing mirror is a reflective oxygen‑free copper optical component, diamond‑turned with surface roughness ＜3nm and surface accuracy ＜0.5μm. It can focus parallel beams to a focal point or convert divergent beams from fiber output into collimated parallel beams, acting as collimator or focusing mirror in high‑power laser systems. The oxygen‑free copper substrate rapidly dissipates heat under water cooling, preventing thermal deformation and maintaining stable spot quality under continuous high‑power operation.

Typical Applications
High‑power laser collimation, laser focusing, laser welding, laser cladding, laser quenching, semiconductor laser optics, CO₂ laser optics.

Standard Multi‑zone Beam Integrator Mirror & Applications
The beam integrator mirror is also made of oxygen‑free copper with diamond turning, surface roughness ＜3nm and surface accuracy ＜0.5μm. Its surface is structured as multi‑zone reflective inclined facets. The incident laser beam is split into multiple sub‑beams, which are reflected and overlapped in the target area to form a uniform flat‑top spot. Water‑cooling design suppresses temperature rise and thermal distortion under high power, ensuring stable spot uniformity and avoiding local overheating of workpiece.

Typical Applications
Laser cladding, additive manufacturing, laser quenching, surface modification, laser edge heating.
