I have laboriously and carefully tested most commonly known/used laser diodes.
All diodes measured using a brand new Sanwu LPM-20T, using the exact same G2 lens at 20cm distance between LD and LPM.
Diodes were maintained at 21°C using a TEC. All diodes were pressed into the same DTR 25mm copper module.

Enjoy!

Most of these diodes are available for purchase in my store.

Here is the complete test data spreadsheet for those who are curious:

I've updated the graphs, you can now click them to visit the interactive version which is easier to read individual diode measurements.
 
If anyone has any requests, please add them to the thread
All diodes already in the list are already planned to be tested eventually when I have the time
