Developed to meet highest expectations

Tracing its origin to worlds first commercial supplier of optical frequency-combs, Menlo Systems has been leveraging innovation in ultra-stable laser technology for over 20 years. As a result, today we offer a portfolio of femtosecond fiber lasers with unprecedented phase-noise performance based on our proprietary figure 9® mode locking technology 1,2 meeting scientific precision and with industrial robustness.

Robust. Reliable. Ready to use.

Core of figure 9® is an all polarization-maintaining fiber design, efficiently decoupling the laser cavity from perturbations such as vibrations and temperature variation. The technology contains no critical or life time limiting components, such as degradable optics. Whether designed to serve science or industry, our femtosecond fiber lasers share exceptional performance:

  •  Robust.
    A single well-defined mode lock state guarantees robust self-start and mode locked operation within seconds – even in harshest environments.
  • Reliable.
    Reproducible laser performance You can rely on even after thousands of on-off turns– with excellent power stability, pulse-to-pulse repeatability, and unsurpassed relative intensity noise (RIN).
  • Ready to use.
    After installation with the switch of a key, our lasers are maintenance-free and thermally managed without any external cooling.
