Large-Offset Phase Locks Application Note

8 December, 2015 App Notes 0 comments

We are pleased to provide an application note on the use of the D2-135 Offset Phase Lock Servo to acquire phase locks with frequency offsets to 43 GHz and potentially higher.

Sideband Locking Application Note

Normally the D2-135 OPLS is used to obtain a phase lock between slave and master lasers with a user-selected frequency offset of between 250 MHz and 9.3 GHz.  By applying sidebands to the master laser via a Mach-Zehnder Modulator, it becomes possible to lock with a much larger frequency offset.
