Primus

High power. Ultra-low noise.

The Stuttgart Instruments Primus is an ultrafast, mode-locked femtosecond oscillator, based on solid-state technology. It combines high average output power with a superior low noise level and excellent power stability. It is perfectly suited as pump source for frequency converters like the Alpha. The entire system is encapsulated in a solid CNC-cut and water-cooled housing, thus reaching excellent robustness against external perturbations.
