With the launch of the ORC-Micro, Menlo Systems is expanding the optical reference cavities portfolio for all telecom applications that require short-term (10 ms) laser stabilization and sub-kHz stability performance. The new cavity is characterized by an extremely compact form factor with a vacuum-free aluminum enclosure and it provides a > 50k Finesse at 1542 or 1550 nm, both in free-space (standard) and with fiber in- and out-coupling (option) configurations for plug-and-play operation, allowing also temperature tunability by means of a Peltier element.
In addition to fiber in-coupling, available options include a TEC controller and the SYNCRO module including laser (wavelength: 1542 / 1550 nm) with servo loop electronics for Pound-Drever-Hall laser frequency stabilization.
For demanding quantum-computing applications that require coupling and locking of two lasers (with different wavelengths) simultaneously to the same cavity, a package option with complementary optics mounted on the ORC-Cubic coupling platforms is now available.
In addition, a module for cubic cavities including vibration-isolation platform has been engineered for a 19″ rack mounting kit.
Lastly, custom ORC-Cubic systems with two-color coatings down to about 370 nm will ensure operation also in wavelength regions challenged by scattering and absorption losses.
For 2025, we have been reviewing the whole portfolio of Ultrastable Laser Systems in order to provide better specifications, while at the same time aligning options and extensions that can be purchased for the top-performing products (ORS and ORS-Compact).
The ORS, ORS-Compact and ORS-Mini products will all benefit from improvements both in the short-term and in the long-term stability.
The stability of the standard ORS has been improved to < 1 × 10–15, whereas the ORS-Compact is now characterized by a better stability of < 2 × 10–15. Additionally, the stability of the ORS-Mini has been also improved to < 3 × 10–15.
The long-term performance (up to 10 ks) of the ORS-Compact and the ORS-Mini has been characterized to provide stable and reliable ultrastable laser systems for quantum computing applications.
Finally, stay tuned for a new ORS thermal shielding design which would allow better control over thermal non-liner drifts to be achieved also for clock applications.
