Hey they both would scare me. I'm nervous just pointing my GGW around.
You're up early/late Dave.

..or a reliable 500mw..?
i am sure that germany went further than almost all other countries, in all aspects. but then again, mankinds phantasy is almost unlimited..
Uhm, about the rated powers ..... we have also to keep in mind that the rated powers that manufacturers say on their specs, are the ones for a normal 50.000 hours continuous working life ..... never seen peoples here that plan to have their BR continuously operating for 50.000 hours .....
But at the same time, also need to keep in mind that degradation on overpower is an exponential curve, not a linear one ..... and also usually the graphs are referred to overpower a LD in CW mode, referred to its pulsed power as comparison ..... IF (with a lot of uncertainity) a diode is rated for 250mW CW, what can be expected at 500 mW CW ? ..... 1500 hours ? .... 2000 ? ..... and at 750 mW ? ..... a pair of hours with a lot of luck, probably ?
Personally, also if a 12X can be pushed to 700mW with no ideas about the life expectance, i may be happy to use it at 500 / 550 mW, well heatsinked, for have a possibility of some more hours of life (especially considering their cost )
EDIT: Otherwise, since high efficiency 8x's can clearly be set to 500mW at least for a while, i would be willing to set my first personal 12x there!
While i have no clue about the number of hours it'll survive, it will surelly be quite a bit more than an 8x would...
..... setting PHRs to 150-200mW .....
Igor do you already have a 12X burner on order for yourself? -Glenn
totally agree, these details are up to you, igor!
i said test the first diode at 400mW output, but your point is true. so lets see how much off the two lowest are, compared to the others?

Ha lasers scare you Tech? Shame shame :tsk:
I didn't start the thread jack, but I may as well finish it...
