ORC-Micro
(Optical Reference Cavity)
Compact Optical Reference Cavity for sub-kHz Stability and Short-Term Laser Stabilization
The ORC-Micro is the most price-sensitive optical reference cavity with reduced form factor for linewidth reduction and short-term laser stabilization, ideal for all applications for which the ultimate performance provided by the ORC-Cubic and ORC-Cylindric is not required.
The ORC-Micro allows to couple an external laser in free-space through a viewport while monitoring the transmission output signal.
Moreover, it offers tunability with temperature via a Peltier element.
Optionally, it provides the possibility to support laser incoupling and outcoupling with FC/APC collimators.
