This is a continuation of this post.

We figured out how to modulate the teraxion laser. TLDR: You must enable the internal frequency locking system before the LXM-U will allow you to externally modulate. This is done through the LXM-Control software. You know it is locked when the software says its locked.

A quick few couple of tests we performed:

1) We cannot scan over a full FSR of the OFCs on this laser with 1550 light. The spec sheet says we should be able to (.2 GHz scan range at max amplitude of +/- 2.5 volts, .2 GHz > FSR).

2) We wanted to adjust the nominal wavelength of the laser to match the thorlabs so that we don't have to adjust the temperature controller of the SHG. We did not actually test this as the manual suggests we will only be change it by +/- .2 nm (and the nominal wavelength is 1551.21nm).

3) I performed the same test as in the above linked post. This shows a similar ringing up when the controller is too higher, but at a slightly different frequency. There is also a similar more broadband increase in noise as the controller gain increases.
