Extending the Offset Frequency Range of the D2-135 Offset Phase Lock Servo by “Indirect” Locking
April 5, 2024| Posted in Application Notes| 2055
Some work requires two lasers to be locked with larger offset frequencies. In
this application note we demonstrate a method for achieving offsets of at least 43 GHz with indications that with the proper equipment the offset could be extended to 100 GHz or more.
