Newport SR-UCC universal cavity controller

The Newport SR-UCC Universal Cavity Controller is a precision instrument for active laser cavity management, delivering stable and repeatable performance across research and industrial applications. It actively controls critical cavity parameters—temperature and piezoelectric (PZT) drive voltage—to maintain optimal optical alignment and system stability. The controller integrates fringe lock control, selectable gain adjustment, and switchable filtering to support both real-time monitoring and oscilloscope-based diagnostics.

– Technical Specifications

• PZT drive voltage for piezoelectric actuator control
• Active cavity temperature stabilization
• Fringe lock control functionality
• Four-position selectable gain with automatic offset compensation
• Switchable 10 kHz filter for oscilloscope operation
• Digital display with panel mount form factor
• Output signals for oscilloscope display (detector and controller outputs)
• Detector Cable and Piezo Cable included

– Key Features

The four-position gain selector with automatic offset compensation simplifies tuning across different cavity configurations and signal levels. The switchable 10 kHz low-pass filter reduces high-frequency noise for cleaner oscilloscope traces during diagnostic work. Dual output channels—one from the detector path and one from the controller—enable simultaneous monitoring of cavity feedback and error signals. Temperature stabilization maintains cavity resonance within tight tolerances, critical for long-term frequency stability in laser systems.

– Typical Applications

• Laser output stabilization through active cavity parameter control
• Optical spectrum analyzer cavity conditioning
• Precision laser frequency locking and tuning
• Real-time cavity performance monitoring via oscilloscope interface

– Compatibility & Integration

The SR-UCC is engineered for operation with all Newport SuperCavity and HiRez optical spectrum analyzers. Direct oscilloscope connectivity via dedicated output connectors allows engineers to observe detector signals and control error signals in real time. The included detector and piezo cables simplify system integration without additional procurement.
