Optical Path Design

Laser cladding is a process involving the interaction of laser, powder flow, gas flow, and molten pool, where the energy distribution of the laser spot plays a crucial role. Yunding Optoelectronics achieves beam energy distribution from Gaussian/near-Gaussian to flat-top intensity profiles through high-quality optical components, obtaining circular, square, or rectangular spots that meet laser cladding requirements, thereby enabling ultra-high-speed, rapid, and broadband laser cladding processing.

All laser equipment in our company uses the highest quality optical components worldwide, including focusing mirrors, roof mirrors, integrators, spherical mirrors, protective lenses, etc. The mirrors are manufactured using air-bearing diamond ultra-precision machine tools, achieving nanometer-level control accuracy. Oxygen-free copper (OFHC) is used as the material for mirrors and integrators to achieve high reflectivity and low scattering characteristics. The materials undergo heat treatment to stabilize surface performance, suitable for long-term use. The surfaces of mirrors and integrators are directly milled or turned by air-bearing ultra-precision machine tools, achieving submicron surface accuracy and nanometer-level surface roughness, resulting in outstanding optical efficiency. To enhance the optical properties (reflectivity and polarization performance) and mechanical properties (scratch resistance, corrosion resistance) of the mirrors, all metal mirrors and integrators are vacuum coated.

When laser power reaches tens of kilowatts, the light guiding system experiences thermal load. Our company eliminates thermal load by providing carefully manufactured water coolers (e.g., spiral water coolers installed at the bottom of mirrors). The top and bottom edges of the mirrors are welded together using internal fusion welding technology. Automatic shut-off cooling water connectors facilitate removing the mirrors from laser processing equipment for cleaning, wiping, and maintenance.
