I turned on the temperature control and TEC for the North laser with the TED 200C laser controller to measure the power dependence on temperature.
The power was measured right after the fiber launch. Laser -> Faraday Isolator -> Intensity modulator -> 90% PO -> Fiber launch
The data and code for plotting is in Attachment 1.
The plot is in Attachment 2.
While the sensor resistance decreased (corresponding to an increase in the laser temperature) an abrupt decrease in power was seen at 8.72  0.01 kOhms [close to 28 C];
When decreasing the temperature (measured by an increasing sensor resistance) an abrupt increase in measured power was seen at 10.23  0.01 kOhms [close to 24 C].
The two sensor resistance values for abrupt power change was determined visually from the graph.
