FLINT high-repetition-rate femtosecond oscillators deliver state-of-the-art output parameters. Built on the proven industrial-grade design of the CARBIDE and PHAROS laser series, FLINT oscillators ensure excellent performance and long-term stability.

The latest model, FLINT-FL2, offers output power of up to 20 W, pulse energy of up to 0.5 µJ, and pulse duration down to 50 fs at repetition rates of 10, 40, or 80 MHz.
FLINT-FL1 oscillators support carrier-envelope phase (CEP) stabilization or repetition rate locking (RRL) to an external source, with selectable repetition rates ranging from 60 to 100 MHz.

To meet the demands of both industrial and scientific applications, FLINT models are available in standard and short-pulse (SP) configurations. Additionally, an automated and fully integrated harmonic generator provides second harmonic (515 nm) output, while the third (343 nm) and fourth (257 nm) harmonics are obtainable using the HIRO external harmonic generator.
