Description

FLINT is a series of femtosecond Yb oscillators providing industrial-grade design and state-of-the-art output parameters such as 20 W output power at 76 MHz repetition rate and sub-40 fs pulse duration. FLINT oscillators are based on Kerr-lens mode-locking. Once started, the mode-locking remains stable over a long time. Furthermore, oscillator cavity length can be adjusted with an optional piezo actuator. FLINT oscillators support carrier-envelope phase (CEP) stabilization and repetition rate locking to an external source.

Automated Second Harmonic Generator

FLINT oscillators equipped with an automated second harmonic generator (HG) provide a selection of fundamental (1035 nm) or second harmonic (517 nm) outputs using software control. In case fundamental and second harmonic outputs are required simultaneously, then HIRO harmonic generator is the solution.

CEP Stabilization

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.

Repetition Rate Locking

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.
