Optical Frequency Comb

Description
SmartComb is an optical metrology system in a revolutionary compact package. In just 19” 3U it features the first fully automated turn-key optical frequency comb designed and built for use both in- and outside the optics lab. It measures your optical frequency anywhere between 530-2000 nm. Feed in your laser and get the frequency with 14 digits. Alternatively, it provides you with optical reference lines in the same spectral range (choose wavelength on ordering).

With its internal RF-reference, SmartComb can be used as a standalone device. For highest precision measurements, a radio frequency or an optical reference input is available to stabilize the SmartComb.

Due to its modular design, SmartComb is one of the most versatile frequency comb system on the market: Internal units can be adapted to measure different wavelengths or be replaced with amplifiers to provide up to 6 output ports. Additional external modules are retrofittable, to provide higher powers, customized spectra and pulse lengths. SmartComb has a robust design. Its underlying proprietary technology based on figure 9^® lasers has already been verified onboard of aircraft and sounding rockets, proving it is well-suited even for demanding environments.

Description
The FC1500-250-ULN Ultra Low Noise Optical Frequency Comb is a compact and versatile fiber-based metrology system. Laser operation relies on the figure 9^® mode locking technology, which ensures excellent stability and low-noise operation. The femtosecond laser is ready-to-use at the press of a single button, and automatic phase lock loops ensure easy stabilization to either a RF or an optical reference. Thanks to the mature system design, users report long-term uninterrupted operation. With a variety of extension packages and add-ons, systems are exactly tailored to the individual experimental requirements.
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 FC1500-250-ULN 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 stability is evaluated in an out of loop comparison between two independent optical frequency combs, which is integral part of the quality check during factory acceptance of each system. Choose between two variants, depending on the stability and accuracy that you require in your lab.

Description
The Menlo Systems FC1500-ULN^plus Ultra Low Noise Optical Frequency Comb is the ideal clockwork for optical lattice clocks. Our all polarization maintaining figure 9^® mode locking technology together with high bandwidth actuators (>1 MHz) for both the carrier-envelope offset frequency and the repetition rate guarantees ultimate performance.

Ever increasing demands for stability and accuracy of time and frequency signals require improved oscillators and frequency references. Today’s best optical clocks rely on narrowband optical transitions and use a frequency comb as a clockwork. The FC1500-ULN^plus clearly keeps pace with the best optical lattice clocks, which is proven in an out of loop comparison between two independent ULN^plus Combs. This comparison is an elementary part of every systems’ quality check at the Menlo factory. Such Menlo guarantees and proves by measurement that the outstanding spectral purity of the oscillator is transferred perfectly to the desired wavelength for every system delivered to the customer.

Description
World-leading optical frequency comb technology is now available in the mid-infrared region. Taking advantage of Menlo Systems’ proprietary figure 9® modelocking 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.
