Menlo Systems has extended the capabilities of their Optical Reference System (ORS) product range with the first models providing output in the visible range. The new ORS-DL series use interference filter cateye design external cavity diode lasers from MOGLabs. These diode lasers, which are known for their robustness, stability, and narrow linewidth, are available at wavelengths such as 657 nm, 689 nm, 698 nm, 729 nm, and many others from 400 nm to 1650 nm. By stabilizing these lasers to high-finesse ULE cavities, Menlo Systems realized sub-Hz linewidths and Allan deviations below 2 x 10 15 at 1 s averaging time. The ORS-DL system includes all control and locking electronics, monitors, vacuum system, temperature stabilization, vibration and acoustic isolation as well.

Menlo Systems’ established ORS1500 system uses a fiber laser at 1542 nm, and quickly found its application in low-noise microwave synthesis and ultra-stable frequency dissemination via optical fiber. The joint effort of Menlo Systems and MOGLabs now makes the state-of-the-art optical reference available to many atomic and molecular physics applications. The attractive solution saves valuable R&D time, enabling the users to focus on the experiments.

The cooperation between Menlo Systems and MOGLabs also aims at combin-ing Menlo Systems frequency comb systems with MOGLabs cateye lasers, offering complete stabilized laser set-ups tailored to the specific needs of our customer’s applications. Such a set-up could include an FC1500-250-ULN Ultra Low Noise Optical Frequency comb locked to an ORS-DL Optical Reference System and several cateye lasers locked to different parts of the comb spectrum via beat detection units, thereby transferring the ultra-high stability throughout the entire visible and infrared spectrum.
