RRE-SYNCRO
(Repetition Rate Synchronization Electronics)
Repetition Rate Stabilization
The RRE-SYNCRO features a dual channel PID controller, an integrated phase detector and integrated amplifier modules for the stabilization of the laser cavity, as well as integrated photo diode modules for laser repetition rate detection at fundamental and harmonic frequencies.
The modular design allows versatile adaptation of the system to all Menlo lasers, and also to a wide range of lasers from other manufacturers.
Features
- Synchronization to Fixed or Tunable Repetition Rate
- Two Stage Locking Scheme Fundamental / Harmonic Phase Relation Defined through Fundamental Lock, Superior Phase Sensitivity Granted through Harmonic Lock
- Support of Third Party Lasers and Actuators
- Integrated Software Control of the Tracking Actuator for Laser Drift Compensation
- Support to Dual Piezo/Dual Integrator Schemes
- Guaranteed and Tested Phase Noise Performance
- Integrated Touch Pad
- Core UI: Software for Operation and Remote Control
- Advanced Phase Rock
- Plug-and-Play Operation
Key Specifications
- RMS Timing Jitter <200 fs (0.1 Hz - 500 kHz)
Applications
- Laser Stabilization
- Synchronization and Timing
- Pump and Probe Spectroscopy
Options
- Custom Reference Frequencies
depending on filter availability
- Custom Phase Detectors
for low drift
- External RF Phase Detector Option
for reference frequency >1 GHz and enahnced timing jitter performance
- Adjustable Offset
to set the relative time delay between the laser pulses and the refence signal, enabling time-resolved experiments without using a mechanical delay stage
- Tunable Repetition Rate
- Repetition Rate Lock Automation
enabled by our Core UI-Control software
- Reference generation electronics
10/20 MHz clock module higher harmonic reference generation via integrated Phase Locked Oscillator
