Menlo Systems introduces its newest platform for metrology: The SmartComb 250, a compact, robust, high-end, and fully automated Frequency Comb sys-tem. This turnkey all-in-one system, built with Menlo Systems’ robust and reli-able figure 9® fiber mode-locked oscillator technology, combines the unrivalled performance of our ultra-low-noise (ULN) frequency comb with a compact form factor of only 3 height units in a 19” rack format.
Essentially a smaller, modified version of the FC1500-ULNnova, the Smart-Comb 250 offers a repetition rate of 250 MHz, leading to improvements over the SmartComb 100 in terms of higher average optical power, better stability and lower phase-noise. Additionally, the SmartComb 250 can be combined with all extensions compatible with the FC1500-ULNnova, enabling an expan-sion of the comb spectrum from 500 nm to 2100nm. Thus, the SmartComb 250 expands its range of applications.
With its increased repetition rate and tunable carrier envelope offset frequen-cy, the SmartComb 250 offers the user the flexibility of adapting the absolute positions of all comb lines. This feature is crucial for the exact matching of in-dividual comb lines to different atomic transitions or analysis/enhancement cavities.

Enabling laser stabilization through Optical Reference Cavities with an unprecedented form factor
Menlo Systems announces the release of the ORC-Micro: the optical reference cavity with the most compact form factor, perfect for all applications that re-quire short-term (10 ms) laser stabilization and sub-kHz stability performance.
With a free spectral range (FSR) of 4 GHz and a finesse of >50k, the newly-developed cavity provides price-sensitive single-color (1542/1550 nm) optical reference options, both in free-space and fiber coupled configurations. It has been designed to provide a cost-effective yet stable reference for applications such as laser cooling and thermal beam experiments.
In the standard free-space solution, an external laser can be coupled to the ORC-Micro through a viewport, while monitoring the transmission output sig-nal. Temperature tuning and stabilization is provided via a Peltier element. The power to customize is in the hands of the user via various options, including fi-ber-coupling and Pound-Drever-Hall (PDH) locking electronics. With the fiber in- and out-coupling setup the user has a plug-and-play solution for telecom laser-stabilization applications.
Finally, the considerably reduced form factor of the ORC-Micro perfectly ena-bles seamless OEM integration, in synergy with other Menlo Systems’ prod-ucts. Don’t hesitate to contact us with you requirements.
