All-Digital Servo Module
Precilasers has launched an all-digital servo module for laser frequency stabilization. Integrated with modulation-demodulation and PID modules, this controller can perform the full workflow including frequency sweeping, error signal generation and laser frequency locking. It supports waveform display of relevant signals and provides locking control for multiple mainstream frequency stabilization techniques, such as absorption spectroscopy, saturated absorption spectroscopy, modulation spectroscopy, modulation transfer spectroscopy and PDH technique. A high-voltage module is available as an option to drive high-voltage PZT.
