Datasheet for the Osram PL 530: http://optoengine.com/images/Documents/OEMLasers/PL530.pdfHello neighbor. I'm not sure about coherence length as the Osram 530nm lasers. I also don't have the pinout diagram and the Vf, current, etc.
Has pinout and Vf/If. Doesn't talk about the PPLN xtal heater but I figured that out based on the research paper.(http://genis.ca/documents/lasers/osram/OsramOPSL-ResearchPaper.pdf).
Driving the heater on mine at around 1.5V with an LM317, seems to be happy with that. AFAIR I used the power values from the research paper and the resistance values in the datasheet to calculate the voltage and current requirements for the heater. Should be happy anywhere between 1.5V and 2.0V.
Have heard mixed information saying that output power and stability are very sensitive in regards to heater voltage, but haven't noticed that from a purely visual perspective. Might notice it if I had a power meter fast enough and sensitive enough to measure the fluctuations.
