- Optical-to-electrical beat note conversion
- 250 MHz to >9.3 GHz
- 760 to 855 nm
- Does not consume ICE slot
The ICE-BD1 is a “piggy-back” board that rides on the ICE-CP1 current and phase lock board. It does not consume duty-board capacity of the ICE-MC1 master and control board. It receives an optical beat note via an SC multimode fiber input and converts it to an electrical signal that can be processed by the ICE-CP1 to phase lock a slave laser to its master with a user-selectable frequency offset of between 250 MHz and >9.3 GHz. Simply overlap the master and slave lasers and launch into the included multimode fiber for measuring the relative frequencies of the two lasers. The ICE-BD1 is compatible with the D2-250 Heterodyne Module or build your own heterodyne optics. In combination with the ICE-CP1, a true phase lock between a pair of lasers with the capture range of a frequency lock can be established.
This digitizing high-speed pre-amplified detector converts an oscillating optical signal (a beat note) into and electrical high/low signal. It works great for measuring beat note frequencies or high-speed timing. It is not suitable for measuring optical power or other amplitude characteristics due to the digitized output.
The ICE system is under your control via serial commands or the ICE GUI. A PC-compatible computer (not included in purchase) is necessary for this control.
