Quad Red.. Who HAs a Working Build?

[Laserman532]

well that's quite straightforward when you think about it

all is a matter of emitter size and diffraction

high power diodes have a BIG emitter size (unless focused in a small core diameter fiber, but other limitations apply) so they are really messy to deal with when using other optics than mirrors

smaller emitter size (as for our small 200mW diodes) are far more diffraction limited so you can use a telescope and, with even fatter beams, obtain collimated light over a greater distance

you hit it right on the head there shrad. The fiber solution is the only way to go IMHO. I have a design for a whole series of products based around fiber combiners however the PL marketplace would not provide a reasonable ROI (in time and money) sadly to say.

GEEESH ! ,

How Many 642nm diodes , do you have to combine, to get 4 watts of red?

[LaserGuy216]

any heads up on bare 635nm diodes??? i want to use thos with dichros to get the best beam over all..

635 bare diodes ? you have to take a PAR36....
(I'm bad, sorry)

ha ha ha ha ...... sooooo funny

PAR36..................................... wow .... that sounds like a big diode......

that info is about as useful as tits on a boar .....

[kl79]

Sorry ....it was easy..

I think it's possible to improve the spot of those bare, but who will find the good lenses ? and the price ?

[LaserGuy216]

if I try to follow this lay out I still get a line in the center of my beam???? any luck.....

[Laserman532]

how are you able to shoot two beams on top of each other. IIRC you have two dual aixiz holders that will not allow that to occur. You would need 4 separate aixiz holders so that one can be shimmed.

Did you not understand my post ?
You will never get the beams to line up
unless the diodes are set to the correct height
been there got the tee shirt and learned the hard way

I think you have misunderstood the action of the PBS cube.
