Optical Reference Cavities

NEW PRODUCT: ORC-Micro

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 1550nm, 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 incoupling, available options include a TEC controller and the SYNCRO module including laser (wavelength: 1542/1550nm) with servo loop electronics for Pound-Drever-Hall laser frequency stabilization.

 

ORC-Cubic

For demanding quantum-computing applications that require to couple and lock 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 cubical 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 370nm will ensure operation also in wavelength regions challenged by scattering and absorption losses.

Ultrastable Laser Systems

Improved short-term stability (MADEV at 1 s) of standard systems (with ULE-IBS)

The stability of the standard ORS has been improved to <1 x 10^-15 , whereas the ORS-Compact is now characterized by a better stability of <2 x 10^-15 . Finally, the stability of the ORS-Mini has been also improved to <3 x 10^-15.

Enhanced long-term stability of standard systems (with ULE-IBS)

The long-term performance (up to 10ks) 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 to achieve better control over thermal non-liner drifts also for clock applications.
