The laser power generated by patented beam coupling
of fibre lasers was successfully demonstrated for the first time in the world.
Key elements of the optical system include the beam path design with its maximum optical precision and the uncompromising concentration on the essentials, the beam combiner system for extremely accurate beam coupling
and superimposition, the beam splitter with continuous and loss-free splitting of the light spectrum and, last but not least, the extremely stable pinhole.
The multiple cut design provides higher torsional stiffness and torque capabilities, and greatly reduced wind-up when compared to a commodity-type single beam coupling
The bellows flexible coupling has the best torsional stiffness -- [greater than] 22,000 ounce-inches per radian -- followed by the slotted radial beam coupling
at 16,000 ounce-inches per radian.
And, in some cases, Ricker said, a single-piece beam coupling
could work in a smaller space than an equivalent bellows coupling, making for lower inertia.
Ruland Manufacturing Company (Marlborough, MA) has introduced a new clamp design for its zero-backlash flexible beam couplings
Helical claims that it is the only company to manufacture beam couplings
out of 17-4PH stainless steel.
