HIRO is a harmonic generator for PHAROS and CARBIDE lasers, as well as FLINT oscillators. It provides a high‑efficiency second, third, fourth, and fifth harmonic at 515, 343, 258, and 206 nm, respectively. The selection of an active harmonic is manual but requires less than a few seconds, thanks to its unique optomechanical design.

The HIRO harmonic generator for PHAROS and CARBIDE comes in three models: standard, high-power (HP), and high-energy (HE), to perfectly fit the pump laser. The standard HIRO accepts up to 20 W and 1 mJ pump, the high‑power model (HIRO‑HP) takes up to 80 W, and the high‑energy model (HIRO-HE) goes up to 80 W and 4 mJ pump while maintaining the high conversion efficiency and beam quality. Also, HIRO‑HP and HIRO‑HE are optimized for high stability and temperature control, while the standard HIRO is customizable with options such as beam size control, collimation, and white-light continuum generation. All models use beam division and harmonics splitting to enable simultaneous or switchable outputs.

Coupled with FLINT, the HIRO harmonic generator provides second, third or fourth harmonic at a high repetition rate.
