D2-250 Heterodyne Module 
The D2-250 Heterodyne Module is designed to conveniently overlap two lasers to produce an optical beat note.  New kinematic adjustment mounts make it easier and faster than ever to co-align master and slave lasers.  The use of rotatable waveplates at the inputs and polarizing beam splitters allows adjustment of pick off a percentage for accepting a large range of powers.

After conversion of the optical beat note to an electrical signal by the D2-260 Beat Note Detector or another fast detector, the electrical signal is delivered to the D2-135 Offset Phase Lock Servo, which compares the divided-down beat note with either an internal or user-supplied reference signal, and locks the slave laser tightly to maintain the desired offset from the master.  The D2-250 is easy to align and only requires a small percentage of the total laser power from the two lasers.
