D2-260 Beat Note Detector

Features:

• Optical-to-electrical beat note conversion
• Detect optical beat note
• Compatible with D2-150 and D2-250 Heterodyne Modules, D2-135-SMA OPLS, and ICE-CP1

The Vescent D2-260 high-speed detector has a full 9+ GHz bandwidth for capturing beat notes between lasers of different frequencies. Simply overlap the master and follower lasers and launch them into the included multimode fiber for measuring the relative frequencies of the two lasers. The D2-260 is compatible with both the Vescent D2-150 Heterodyne Module and D2-250 Heterodyne Module and the D2-135 Offset Phase Lock Servo. In combination, a true phase lock between a pair of lasers, with a user-defined, high-precision frequency offset, can be established. The D2-260 is also compatible with the ICE (Integrated Control Electronics) architecture. This digitizing high-speed pre-amplified detector converts an oscillating optical signal (a beat note) into an RF beat note. It works great for measuring beat note frequencies. It is not suitable for measuring optical power or other amplitude characteristics due to the digitized output.

When purchasing the D2-260 with a SLICE-OPL Offset Phase Lock Servo, purchase a D2-260-PS +5 VDC Power Supply.
