Need some help planning/building RGB scanner

Oh and the 636nm aint gonna happen as far as I can tell. apologies for the teaser.
I guess I can devulge it now; I bought 5 pc mitsubishi 150mw 636nm diodes .. 5 x 38 divergence. Chuck cant do anything with 'em and I know j.sht about optics and they charged me 1500 when it was supposed to be $295 total instead of 'EACH' so..legal dispute is in effect. Any optics experts out there?? It is a brilliant (although unusable) color tho...
for sale.. unless I have to return them..

OK, I posted that late last nite. <cough> I'll re-iterate.
A few months ago I bought 5 samples of mitsu 636 nm 150 mW laser diodes. There was interest from a professional laser builder that we all know and love also, so I got a quote from a distributor thru a sales rep for 295usd total for the 5 pc (being samples and prototypes this seemed fair to me, especially since the sales rep offered 1 for free if I wanted- (I should have gone that route, knowing now what I know now.) I received the LDs in about 2 months and sent one diode to Mr. C, and kept 1 to experiment with myself. It is a beautiful color and extremely bright!!

A couple weeks later I received a small "sales receipt" with a total of $ 1500 dollars In dibelief I immediately called the distributor and told her no way I could pay this amount, she said she'd talk to mitsubishi.. a week or 2 went by so I emailed the rep. He responded saying he'd talk to her. No responses now at all so I'm beginning legal proceedings against them and mitsu using visa-card's dipute services to hopefully recover some losses.

I have built a PS, driver and mount and am beginning the optics experimentation. I've had the best luck so far with a small aspheric lens from an old PC CD player but havent had any time to do much. I am beginning this morning (if nothing comes up ) and hope to make progress. Any input is welcome. If the dispute cannot be resolved I may sell (3) of these diodes on the buy/sell/trade forum. The dispute is all done in hard-copy thru the USPS using a 3d party un-biased service used by visa so it may be a while. Thanks for reading my lengthy story.
Well, I'd better get busy. Oh, and here are the diode specs and a few pics
I dont know why it looks blue, its really red; cheap web-cam overload I guess. The PDF file is on the very bottom. The specs on these are actually better than the published ones.

Hold the phone.. partial success.. all it took was some tinkering and a few hours Definitely not perfect and not TEM00, but 636 nm yes There may be hope yet Wheee!!!

[marconi]

Yep, thats about what I got out of one of these...
Still not quite good enough..I still need to rip the top of the can off...

[steve-o]

So youre still gonna work on it Chuck? Great!!! Cant wait to see your results

[mliptack]

So let me ask you. Why 636nm? Did you anticipate them to be better than 635nm's beam specs?

[steve-o]

I'm assuming that question was meant for Marconi; he's the optics expert..

Hi steve-o sounds like you need one of these or something like it, if your trying to squeeze the fast axis in on the outside of the can you will need a 3 or 4 mm at a guess.

636nm is what was spec'd on these..Close enough to 635.
at least my eyes wont know the difference

Yeah, These diodes are gunna need some work..prying the top off the can for starters will help to get closer to add a microlens.
Its gunna need it..
Without opening the can...The anamorphics wernt enough, I tried.

[steve-o]

Yeah the slow axis on these is great. The F/A needs the work . Thanks for the info. How did you figure 3-4 mm?
