ORS-DL Optical Reference System – ultra-narrow lasers in the visible range
Menlo Systems’ new Optical Reference System series in the visible range can save you valuable R&D time, enabling you to focus on your experiments. We provide an all-in-one complete system delivering as many ultra-narrow laser lines as needed.

The ORS-DL series use interference filter cateye design external cavity diode lasers from MOGLabs. These diode lasers, 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 ORS-DL now makes the state-of-the-art optical reference available to many atomic and molecular physics applications.


Transfer of the sub-Hz linewidth from the ORS-DL to several other diode lasers via Menlo’ FC1500-250-ULN

Combining Menlo's frequency combs with our optical reference offers a complete stabilized laser set-up tailored to the specific needs of your application. 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 diode 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.
