Menlo Systems’ fiber-based femtosecond laser sources integrate the latest achievements in fiber technology into easy-to-use products. Menlo Systems’ unique figure 9® design results in reproducible and long-term stable operation. It is based on the well-established nonlinear optical loop mirror (NOLM) mode locking mechanism. Both oscillator and amplifier use polarization maintaining (PM) fiber components only, ensuring excellent stability and low-noise operation. The laser is maintenance free, user installed and ready to use at the press of a single button. Customize your laser with the available options to match the requirements of your application.

    Synchronization: Laser to reference

    Synchronization Laser ReferenceRelative Phase Noise between stabilized laser and 10 MHz reference:

    RMS Timing Jitter: <200 fs [0.1 Hz–500 kHz] or same as reference, whichever applies first

    Integrated timing jitter of free running laser: <2 fs [rms, 10 kHz.. 1 MHz]


    Synchronization: Laser to laser

    Synchronization Laser Laser

    Relative Phase Noise between two lasers in master-slave configuration

    RMS Timing Jitter down to <20 fs [0.1 Hz–500 kHz] for Menlo fs lasers as master/slave with small locking bandwidth

    Integrated timing jitter of free running laser: <2 fs [rms, 10 kHz.. 1 MHz]
