Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

[kiyoukan]

yeah i was hoping to get a look at one of those in action
Okay i have to know 2 of these laser connected threw pbs each laser giving out 300mw so around 600mw out.
is there any way i can get this beam to be that of a 445nm laser with a power of 300mw?
im not looking for perfect even if i have to lose 50% can it be done
right now im running a dual lpc-815 for around 500mw of red.
would 2 of those at the lower nm be brighter?

Hey you guys think that fiber optics might help out with this diode? Use a single or multimode fiber then try to use DR optics? It's worth a try even if you guys think it won't work. Who knows, you may be surprised

I think it has grown quite because we have NO answers yet. No further information...from any direction....Will higher magnification Cylinderical lenses provide less divergence ?? Will DRLava sell them ?? When or will the unknown collimination lens be identified ?? Will the results of Andyf97 be duplicated ?? What exactly were his beam geometries at aperture and beam termination ?? ALL UNKNOWNS !! PLUS the other unanswered questions of;

Does anyone have access to Optics simulation programs ?
Has pseudonomen137's mRad Calculator been knife edge verified ?
Are fibre optics a possible beam corrective solution ?( I can answer this one....not without extreme mW loss )

I suppose no answer means NO ? I am at a stand still. My goal would also be to equal the prism correct output of a 445LD. Perhaps this is a dead end !!! Hopefully not !! But if it is...it is !! The quest goes on !! I wish we had some more answers !!!!!! The sooner the better !!!

right now i am using an uncorrected 445nm so im not huge on beam specs.
Would this equal a uncorrected 445nm beam?

[CDBEAM]

Did a quick eyeball look.... My eye sez that the Drlava corrected ML520G71 has slightly less divergence than a uncorrected 445...but has more divergence than a prism corrected 445. By uncorrected 445....I mean only corrected with an O-Like Aspherical Glass lens. This quick look is just an opinion. No measurements were taken and the distance to the target was 4M. The more deeply I get into this....the more I want a some type of CCD set up to accurately measure beam profile !!!

Hmm well i think thats good enough for me then!
I dont think the divergence of the 445nm is to bad.
So its time to order 2 of these diodes then!

CDBEAM I've read up to page 5 so far in this thread. I'm reading the rest now. But what would happen if you used two sets of DRLava lenses?
Would that be a stupid idea?

You're buying me one?? You're too kind Kiyoukan

space jay are you the same jay from place?
and sry no i got to build my projector and have it ready by the 31

I'm just kidding man. Good luck on your projector

Um from what place?
