Lightwave Electronics 2005 Laser Offset Locking Accessory
For sale- a Lightwave Electronics Series 2005 Laser Offset Locking Accessory (LOLA). Somewhere along the line Lightwave Electronics was acquired by JDS Uniphase, which makes finding information on the piece more difficult. Fortunately I have a copy of the manual which provides a product description. An optical heterodyne system consists of two main components: two lasers whose output is mixed together to produce a difference frequency (beat note), and a method of precisely controlling those lasers to give the desired frequency.
Lightwave Electronics Series 2005 Laser Offset Locking Accessory (LOLA) is an electronics unit which controls the difference in optical frequencies between two of Lightwave s tunable Series 122, 123 or 124 , and 125 or 126 Lasers. This difference may be set to a specified frequency or phase locked to an external reference source. The Series 2005 differs form the Series 2000 in that the 2005 has sufficient power supply capacity to drive the higher power 125 & 126 lasers whereas the 2000 did not.
APPLICATIONS: The Series 2005 can be used whenever it is desired to lock two single frequencies together for such diverse uses as: optical delivery of microwave for radar, detector calibration, heterodyne LIDAR operation, and frequency multiplexed optical communications research.
The quotes are taken from the manual, I have to assume they know what they are talking about. The surplus condition code would theoretically indicate the piece is functional, and it powers up as you can see and I was able to toggle through some of the menus no problem.
OK, there was an initial problem, it indicated the interlock was open even though the little loop connector was present on the back panel. I opened it up trying to determine if the Low Noise Clock option is installed (far as I can tell it is not) and found that the Interlock connection inside the unit was not plugged into the board. After that everything seemed fine. It would appear to me to be functional, but it is untested other than as described, an no warranty is offered.
