Menlo Systems Optical Frequency Combs Information
FC1500-Quantum
The unique patented Menlo comb technologies allow the transfer of spectral purity, narrow linewidth, and high stability of the ORS throughout the entire comb spectrum, and enable the down-division to the RF domain without any loss of phase coherence. The purity transfer is future proof, with the residual comb phase noise being orders of magnitude below the highest stability optical reference demonstrated to date. These features enable the minimization of the Dick effect in optical clocks, high phase coherence to maximize optical and microwave qubit fidelities, and last but not least, 24/7 cycle-slip-free and drift-compensated laser operation. The FC1500-Quantum is ready to enable and enhance your state-of-the-art Quantum Application.
SmartComb-ULN
Menlo Systems introduces its newest platform for metrology: The SmartComb-ULN, a compact, robust, high-end, and fully-automated Frequency Comb system. This turnkey, all-in-one device, built with Menlo Systems’ robust and reliable figure 9® fiber mode-locked oscillator technology, combines the unrivaled performance of our ultra-low-noise (ULN) frequency comb with a compact form factor of only 3 height units (3U) in a 19″ rack format. 6 output ports are readily available to either directly interact with your application in the Er-band or seed spectral extensions and amplifiers, enabling experiments in the spectral range from 500 nm to 2100 nm. An input port for an optical lock at 1.5 μm is also included.
The SmartComb-ULN ensures that spectral purity and stability are maintained throughout the entire covered spectral domain, making it ideal for use in both mobile and stationary applications, thus providing reliable performance for a wide range of scenarios. Furthermore, the underlying technology has already proven to be suitable for applications in demanding environments such as on-board aircraft and sounding rockets.
FC1500-ULNnova
The FC1500-ULNnova is Menlo System’s latest optical frequency comb synthesizer for ultimate performance. The core of the new model consists of a redesigned comb oscillator, based on the patented ultra-low-noise (ULN) figure 9® mode-locking technology. The enhanced design of this so-called “nova”-oscillator results in significantly improved robustness against acoustic distortion and thermal drift. The major benefit is a reduced free-running linewidth of only 15 kHz. Owing to this leap in linewidth reduction, the FC1500-ULNnova has proven to support a frequency stability on the 10−19 level for 1 s averaging time!
Ever increasing demands for stability and accuracy of time and frequency signals require improved frequency references. But even the best optical references have very limited spectral coverage. The FC1500-ULNnova overcomes these limitations by transferring the spectral purity of a stable reference to the entire wavelength range of 500 – 2000 nm. This unique feature enables the users to compare different (optical) frequency references, stabilize all CW lasers to one absolute frequency reference and use it as a clockwork for optical clocks. The overall frequency stability is evaluated in an out-of-loop comparison between two independent optical frequency combs, which is an integral part of the quality check during factory acceptance of each system.
FC1000
Frequency comb technology makes direct measurement of absolute optical frequencies possible. The FC1000 Optical Frequency Synthesizer is a compact, portable and flexible fiber-based femtosecond frequency comb system. The system is capable of providing at the same time a source for frequency metrology in both the visible and the near-IR regions (520 – 1040 nm) of the spectrum. A wide range of optional units enables us to tailor this versatile system to customer specific metrology solutions.
Mid-IR Comb
World-leading optical frequency comb technology is now available in the mid-infrared region. Taking advantage of Menlo Systems’ proprietary figure 9® mode-locking technology, Menlo Systems’ difference frequency generation (DFG) based Mid-IR combs provide access to the 3 – 14 μm range. The reliable, turn-key mid-IR Comb is an enabling tool for applications in the important fingerprint region for high accuracy spectroscopy or nanoFTIR.
AstroComb
Accurate analysis of the light emitted or absorbed by celestial objects requires spectrographs, which must be precisely calibrated. AstroCombs provide a stable and known set of evenly spaced sharp spectral lines that act as reference points, enabling precise calibration of the spectrograph’s wavelength scale. The comb-like pattern spreads across a wide wavelength range in the visible and near-infrared, and illuminates individual pixels of the spectrograph. The resulting high resolution provided by the AstroComb in any part of the spectrum cannot be achieved with traditional Thorium-Argon (ThAr) calibration lamps.
