D2-135 Offset Phase Lock Servo
D2-135 Offset Phase Lock Servo for locking the phase and offset frequency of a slave laser to that of a master
- Offset Phase Locks up to ≥9.5 GHz
- Feed forward for fast frequency jumping
- Offset Frequency stability determined by external reference stability
- User-adjustable servo loop parameters
- Internal ramp generator
- Options for optical or electronic beat-note input
The D2-135 Offset Phase Lock Servo (OPLS) is designed to precisely control and quickly adjust the frequency detuning between two lasers. The D2-135 provides for an extremely tight phase lock between the master and the slave. The D2-250 Heterodyne Module conveniently enables the overlap and fiber coupling of two laser beams. This mates with a FC fiber connector on the D2-135, providing an easy optical input for the beat note. Alternatively, the fiber connector can be exchanged with an SMA to input an electronic beat-note. One can detect the optical beat note with the D2-260, or a third-party high-speed detector. The D2-135 OPLS provides full servo-loop customization for optimization of most lasers.
The D2-135 integrates into our Rackless Rack. As such, it may be powered with our D2-005 or from an adjacent D2 electronics module. If used as a stand-alone product, it may be powered with either a D2-005, or from a user supplied power supply via a breakout board. View a typical configuration for using the D2-135.
