Description

The rack-mountable ORS-Mini Ultrastable Laser System is designed for field applications and OEM integration. It delivers ultra-narrow linewidth laser light with 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 made out of ultra-low expansion glass (ULE) and is operated in vacuum at the point of 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. The user controls all parameters using either the 7” front-panel touchscreen or a GUI on a remote PC. The onboard software ensures automatic cavity locking and system monitoring.
