The Stuttgart Instruments Primus is a mode-locked femtosecond oscillator with high average power, low relative intensity noise, and a robust, water-cooled housing. It is an ideal pump for the Alpha and for standalone ultrafast experiments.
- Mode-locked femtosecond pulses
- Shot-noise limited at −168 dBc/Hz above ≈100 kHz
- Ideal pump source for the Alpha

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.
Typical applications
- Optical parametric oscillator pumping
