FLINT is a series of Yb-based femtosecond oscillators providing state-of-the-art output parameters. Backed by the proven industrial-grade design that is the core of the PHAROS and CARBIDE laser series, FLINT oscillators ensure excellent performance and stability over a long time.

The latest FLINT-FL2 oscillators offer output power of up to 20 W, pulse energy of up to 0.6 µJ, and pulse duration of down to 50 fs at the repetition rate of 11, 20, 40, or 76 MHz. Also, the second harmonic is available with an automated and fully integrated harmonic generator, while the third and fourth harmonic is obtainable with an external harmonic generator. The FLINT-FL1 oscillators support carrier-envelope phase (CEP) stabilization or repetition rate locking (RRL) to an external source with the repetition rate selection from 60 to 100 MHz. Both FLINT models come in standard and short-pulse configurations to fit the needs of most industrial and scientific applications.

FLINT oscillators equipped with an automated second harmonic generator (HG) provide a selection of fundamental (1H) or second harmonic (2H) outputs using software control. The HG is fully integrated into the industrial-grade system.

In case fundamental and second harmonic outputs are required simultaneously or higher harmonics are required, then HIRO harmonic generator is the solution.

FLINT oscillators can be equipped with feedback electronics for carrier-envelope phase (CEP) stabilization of the output pulses. The carrier-envelope offset (CEO) of the oscillator is actively locked to 1/4th of the repetition rate with a <100 mrad standard deviation.

FLINT oscillators are customizable for repetition rate locking applications. Coupled with the necessary feedback electronics, the repetition rate can be synchronized to an external RF source using the two piezo stages installed inside the cavity.

The repetition rate locking system can assure an integrated timing jitter of less than 200 fs for RF reference frequencies larger than 500 MHz. Continuous phase shifting is available on request.
