Gigajet GHz femtosecond oscillator

Gigajet GHz femtosecond oscillator

Laser Quantum Gigajet series are femtosecond oscillators offering high repetition rates up to 1GHz, 2W average power in pulses that can be as short as 15fs.

The Gigajet series are also available as a dual oscillator version, the Gigajet TWIN, providing a compact realisation of spectroscopy techniques that use two femtosecond lasers. At 1GHz repetition rate, the Gigajet oscillators offer a ten times larger mode spacing and power per mode than conventional systems. Gigajet TWIN enables high-speed ASOPS with <60fs time resolution in combination with Laser Quantum's TL-1000-ASOPS offset stabilisation unit.
