No problem...
This thread is dead and closed, but I guess it still has good information on the O-like Green lasers.
I don't know who the manufacture is, but I can tell you that it is much different than an RPL.
The RPL is a C-mount diode and has a built-in protection circuit. Larger too. Supposed to be a really long lasting diode per the Optotronics site...
"Powerful 2.5 Watt
n-LIGHT IR diode (encased in copper to improve heat transfer) ;
n-LIGHT high reliability IR diode: 80,000 hours MTTF with
BriteLife™ Technology "
And of course the adjustalbe tail cap is trick too! The new ones have 15 positions. Although I only use two on mine. The lowest setting for warm-up, and the highest setting for max power...
Anyway, I'm no expert on DPSS, but I know that there is a lot more to it than just the pump diode. Crystal quality, alignment, and so forth...
On the other hand, the O-like laser will put out a lot of green for the price!
