When they repeatedly use the term "un coated", is that their tech speak for un canned? Or are they referring to something else entirely, like a literal coating on the facet..?I have used a coupler ( made by Rich ) to employ a backwards G2 on an intact GBall diode before, however using another GBall from a sister diode taken from the same block would likely work the best.
Note: The couplers are 12mm wide so the whole thing ( module and coupler ) can be put into a heat sink much like a longer module.
Most people will probably just remove the GBall and maybe keeping it clean will help, there has been some discussions I have read online outside of LPF about facet degradation in multi watt blue laser diodes supposedly due to humidity causing oxide deposits on the facet that result in burn through..........It's possible that current production diodes may be using a coating that may resist this, but it's also suggested that there's a backfill gas inside the can.
HEY........it's a hobby and 465nm is really pretty, try and see, conduct your own testing and enjoy the pretty beams, then report back your findings.
