Latest Patents

Thomas Renner's latest patents include a **Resonator Array for Solid-State Lasers** and a **Laser-Processing Unit with Observation Device**.

The **Resonator Array for Solid-State Lasers** is designed to provide a stable resonator that mitigates thermally induced lensing effects. This patent includes a laser rod, a rear mirror, and a semi-reflecting output mirror. The unique aspect of this invention is the extremely asymmetrical configuration of the rear mirror, which allows the laser rod to be positioned closer to the output mirror. Additionally, the convex curvature of one end of the laser rod achieves a beneficial refractive effect, resulting in improved beam quality even at shorter resonator lengths. The thermal lens effects have minimal impact on processing outcomes, with the starting pulse behavior remaining below detection limits.

The **Laser-Processing Unit with Observation Device** pertains specifically to laser-welding units that employ a laser beam source for generating a laser beam. This invention introduces a pivotable focusing unit capable of pivoting the laser beam around two axes of rotation. A dichroic mirror is strategically arranged within the beam path, allowing for an observation device to align with the laser beam's optical axis as it travels downstream, effectively enhancing operational efficiency and accuracy.
