HIRO is an external harmonic generator for PHAROS and CARBIDE lasers, as well as FLINT oscillators. It provides high‑efficiency second, third, fourth, and fifth harmonics at 515, 343, 257, and 206 nm, respectively. Thanks to its unique optomechanical design, selecting the active harmonic is a manual process that takes only a few seconds.

The HIRO harmonic generator for PHAROS and CARBIDE is available in three models – standard, high-power (HP), and high-energy (HE) – to match the specific requirements of the pump laser. The standard HIRO supports up to 20 W and 1 mJ pump energy, while the high‑power model (HIRO‑HP) handles up to 80 W, and the high‑energy model (HIRO-HE) accommodates up to 80 W and 4 mJ pump energy, maintaining the high conversion efficiency and beam quality. The HIRO‑HP and HIRO‑HE models 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 harmonic splitting to enable simultaneous or switchable outputs.

When paired with the FLINT oscillator, the HIRO external harmonic generator provides second, third, or fourth harmonics at a high repetition rate.
