The Orotig RR Pico laser engraver allows marking details invisible to the naked eye. Thanks to its short laser pulse duration and a spot of 0.05mm, designs as small as 0.1mm can be engraved. With a pulse of 1–3 picoseconds — about 1,000 times shorter than standard laser pulses — the marking process occurs without burning or modifying the structure of the metal, and excess material is vaporized, resulting in a clear, precise, and bur-free marking. The RR Pico is ideal for engraving on finished and rhodium-plated jewelry, streamlining the production process.
