Direction-injection green diodes are still expensive ($300+ a pop) but that isn't going to last. Eventually they will be perfected and will likely replace DPSS green lasers for projection purposes.
But will they replace DPSS pointers to the point that DPSS pointers are hard to obtain, sort of like orange and yellow HeNe's disappearing? I hope they don't, because (assuming green diodes stay near 520nm) the colors are distinctive, and it would be a shame to lose the 532nm color as well as the DPSS beam profile. Maybe diodes will be developed to emit 532nm, but they won't be the same as DPSS.
What do you all think?
