Description
Low-noise high-sensitivity photodetection for precision optical measurements
The PDA amplified photodetector from Santec is a high-performance silicon photodiode system designed for low-noise optical detection applications. Optimised for precision measurements such as cavity locking and laser stabilisation, it delivers high gain, low noise, and stable response across demanding experimental conditions.
Wide dynamic range
Suitable for both weak and moderate optical signals.
Fast response time
Designed for high-bandwidth applications such as PDH locking.
Compact integrated design
Standalone unit with simple power and signal interfaces.
Stable long-term operation
Optimised for continuous laboratory use in feedback systems.
Applications
- Pound–Drever–Hall (PDH) locking
- Optical cavity stabilisation
- Laser frequency stabilisation
- Weak signal detection
- Precision spectroscopy
System Integration
The PDA is commonly used as part of feedback loops in laser stabilisation systems. It integrates directly with our controllers such as FSC and dDLC systems for high-bandwidth optical control.
