The Stuttgart Instruments Primus is a 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.
- Mode-locked femtosecond pulses
- High average output power
- Low relative intensity noise (RIN)
- Ideal pump source for the Alpha

Performance
Shot-noise limited
Typical specifications include power stability < 0.25 %rms and Fourier-limited pulses with a time–bandwidth product below 0.35.
The relative intensity noise figure shows shot-noise limited performance at −168 dBc/Hz from approximately 100 kHz onwards.
