The beams from the Innolight and Lightwave NPROs were both incident on a 1GHZ New Focus PD. Mott and I swept the temperature of the Lightwave and tracked the change in frequency of the beatnote between the two. The Innolight temperature was set to 39.61C although the actual temperature was reported to be 39.62C.
Freq. vs temperature is plotted below in the attached PDF. The slope is 2.8GHz/K.
The data is in the attached MATLAB file.
