HIRO is a customizable free-standing harmonic generator for PHAROS and CARBIDE lasers, and FLINT oscillators. It provides a high-efficiency second, third, and fourth harmonic generation at 515, 343, and 258 nm, respectively. The selection of an active harmonic is manual but requires less than a few seconds thanks to its unique optomechanical design.

HIRO can be customized for additional options such as beam size and collimation adjustment, white light continuum generation, as well as beam division and harmonics splitting, which makes all harmonics available at the same time.
