Tracing its origin to worlds first commercial supplier of optical frequency-combs, Menlo Systems has been leveraging innovation in ultrastable laser technology for over 20 years. Today, we continuously strive to extend a portfolio of femtosecond fiber lasers based on our proprietary figure 9® mode locking technology – meeting scientific precision with industrial robustness.
The ELMO series of 1560 nm erbium lasers delivers up to 380 mW average output power with pulse durations down to 45 fs – industry proven by 24/7 operation in harsh environments.
For 2025 improvements, we increased the output power of the ELMO model to support even more demanding applications like amplifier seeding, THz generation or ultrafast pump-probe spectroscopy. The ELMO module is the starting point for multi-colour outputs and modules in a very compact design with simple plug & play.
The ELMO 780 XHP model is designed for demanding high power applications in 3D nano printing and two-photon microscopy. The new high-power model delivers more than 1 W of average output power at 780 nm, with pulse durations down to 100 fs. Owing to a refined dispersion pre-compensation, these pulse durations can be delivered right to your sample. The integrated AOM allows for fast light modulation. Offering all the versatility of our modular concept, the ELMO 780 High Power fits in seamlessly to our product line of industrial femtosecond fiber lasers – ready for OEM integration.
The XHP model with multicolor ports is also enabling demanding applications in ultrafast pump-probe spectroscopy. The wavelength range could be extended starting from 390 nm up to the visible mid-IR and even to THz.
The YLMO 520, based on frequency doubling of our YLMO 1040 nm Ytterbium femtosecond laser, delivers up to 1 W average output power at 520 nm, with pulse durations below 150 fs. A versatile design permits simultaneous access of the 1040 nm fundamental, at an arbitrary power splitting ratio. High peak powers, excellent stability, and consistent long-term performance make the YLMO-520 a perfect fit to applications such as multiphoton excitation, pump-probe spectroscopy, or two-photon polymerization.
Our proprietary figure 9® fiber laser design is poised to adapt to customized repetition rates, repetition rate tuning, synchronization, asynchronous optical sampling (ASOPS), or carrier envelope phase (CEP) stabilization at exceptionally low noise levels. In 2025, we not only continue to serve these requirements with complete solutions from under one roof – but strive to advance the compactness, cost-effectiveness, and user-friendliness of control electronics to a new level.
Robust. Reliable. Ready-to-use.
Whether THz generation, multiphoton approaches in microscopy and 3D nano-printing, state-of-the-art spectroscopy, seeding of amplifiers, or generation of optical frequency combs – we have your application covered with a femtosecond fiber laser portfolio that perfectly aligns to scientific as well as industrial/OEM settings.

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 the harshest of 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 turn of a key, our lasers are maintenance-free and thermally managed without any external cooling.
