With a whole slew of new blu-ray diodes coming from new drives, being used in new builds, I think it would be a good idea to regather all of these diodes and their graphs into one place. If I were to start a new thread in the general section, that graphed and attached a function to the normal behavior of laser diodes would that lift a lot of the "How much current" threads that are started by new members?
Similar to Dr. Lavas diode roundup, I would like to make a master graph for all reds and blu-rays that we work with. This graph would plot the mathematically averaged results seen from every diode.
So for the plot on the graph that represents what a BDR-203 typically lases in terms of input current vs. its optical power output, I would have to find an average for all the plots seen on FrancoRobs master 8X graph for instance.
I would gather as many graphs as possible from the forum, that plot someone's BDR-203 (or whatever else diode). I would then re-plot them into my graphing program, and use regressional analysis to find a "best fit curve". The program would then give me the equation for this best fit function.
From there, we could use that function, the universally determine what a typical example of a given diode will lase.
... IF I could get diode voltages for the same graphs, then I would go ahead and make efficiency functions for the universal diode. Which would determine the power efficiency of a diode at given currents.
I know LDs are so different in many ways, but to have a function to work with would be valuable to have for every diode we work with.
Hopefully Dave, Igor, and Larry can get in on this too...
collecting the data will take some work!
Tell me what you ALL think..
Could this be beneficial to the forum? Who would be willing to help collect data?
Thank you,
