An orb amplifier is pictured here, specifically the one located within the Forest Array of Koboh's Basalt Forest.
Amplifiers for orbs existed as components within structures dating back to the High Republic Era and were situated on the planet named Koboh. These devices utilized Jedi technology to stabilize, focus, and enhance the volatile potential energy contained within Koboh orbs. The result of this process was the creation of an energy beam that had the ability to repel Koboh dust, and ignited the dust's solid form, causing it to burst into purple flames.
Here is an orb amplifier in operation with an orb, photographed at the Forest Array within Koboh's Basalt Forest.
