The rack-mountable ORS-Mini Ultrastable Laser System is designed for field
applications and OEM integration. It delivers ultra-narrow linewidth laser lightwith excellent frequency stability.
The system’s centerpiece is a high-finesse Fabry-Pérot cavity (cubic spacer
with a length of 5 cm) serving as a reference for a CW laser. The cavity is madeout of ultra-low expansion glass (ULE) and is operated in vacuum at the pointof zero thermal expansion. The reference cavity is acoustically isolated allowing
for excellent performance also in rough laboratory environments. Rigid mounting of the cavity ensures portability without realignment of the optical paths.
The system electronics is based on the newest generation of Menlo Systems’
proprietary SYNCRO controller—a modular platform designed for versatility
and intuitive use. It incorporates all required electronics, e.g., a low-noise laser
driver and a very fast (analog) servo loop for laser frequency stabilization. Theuser controls all parameters using either the 7” front-panel touchscreen or aGUI on a remote PC. The onboard software ensures automatic cavity locking
and system monitoring.
