Well that's just craptastic...regarding the shape, I wonder if due to the correction that those diodes just need a different focal length collimating lens to achieve the correct far field geometry, do you have a G7 or G8 lens you could try? I'm thinking that, similar to a C-lens pair, that...

The thread is a year old so I doubt there's any left...

Yeah, I see that for the 525nm diode, the parallel/perpendicular divergence is 11/11 for the square and 11/1 for the line. It just doesn't make sense that they were able to correct to 1mrad, usually correction is done by expansion and I don't know how expansion could result in both a line AND...

I'm still really confused about the "line" FAC corrected diodes... for three reasons. 1. If the output geometry is a line, whether it's a longer or shorter line than the uncorrected beam.. it's still a line.. is the photo of the spot provided by the seller taken a few inches from the output or...

They seriously need to to do something about that and lower the prices for shipping, charging $45 dollars to ship something that everyone knows costs less than $3 to ship which weighs less than 10 grams is what people expect from scandalous, bottom feeding, dishonest sellers and I know that...

My guess is that they're maybe both the Sharp diodes (that aren't FAC corrected, pretty sure the Sharp diodes aren't offered in FAC) with different wavelengths between samples? That or just the one of the right is the Sharp.. either way I'm pretty sure the Sharp isn't a FAC modified diode...

Seller says they're NUBM08's..

You would still need a lens, the FAC only corrects one axis and it doesn't collimate either axis...

It's interesting, that same seller has what appear to be FAC corrected P73's, FAC USHIO 1W 638's, also FAC NUBM08's with an aftermarket can taking place of the gball (sort of like an N465 with a FAC). The prices are unreasonable, as in, unreasonably cheap. Got to get some of them, they look...

Does your datasheet list the green as .5 or 1 watt?

Interesting that the ebay seller has them up as 500mw units and has a datasheet specifying them at .5W when Sharp has the same model # rated at 1W in their table. I'm excited about the 5W 455nm and 2.5W 638nm units. I'm sure the 638's will have horrible divergence, but whatever, c-lenses.. at...

I had to look this up because I wasn't sure certain but it turns out that a properly heatsinked TO-220 LM-317 is specified as a "minimum" max output of 1.5A and a "typical" maximum continuous output of 2.2A.. For your 1.8 watt 445nm diode you can feed it 1.6 amps by running a 0.8 ohm load...

Hey there! I don't normally say this when I see it.. but since the title of your post indicates your familiarity and understanding of wavelength.. why didn't you post this in the 445nm subforum, even the blue/other color sub would have been more appropriate. This is a serious question, I hope...

YES, 465nm diodes will degrade quickly if you decan the diode!!!

Or PBS combined as mentioned above.. which seems like a great idea as one diode can manage 2.5W using passive cooling, running rated output (more if overdriven) in to a 2.5 watt single axis, overlapped NON knife edged beam if a wave rotator and PBS cube are used.. something just not possible...

Has any more information on these diode arrays been discovered yet? It was a number of weeks ago (months, actually) that at least a couple of members had units undergoing testing and what was shown looked very promising... but vital information such as whether or not the outputs were actually...

Maybe it's just the old LCD projectors that won't need a colli lens on the laser output.. or maybe it's different between manufacturers on whether or not they have that lens in the optic path before the zoom/focus assembly. Either way, thanks for letting us know.

Does the beam need to be collimated(focused to infinity) before its expanded??? I tried that and couldn't get it to work. I'm pretty sure that the adjustable zoom assemblies from projectors also include what amounts to a "collimating" lens in the optics path for the final color summed DMD...

You should perhaps get a Lasorb. Note that this will not prevent you from overdriving your diode, but if you're worried about ESD or current spikes, this is the thing to get. It's the gold standard in laser protection and relatively cheap.. if I remember correctly mine was about 20 dollars...

He would be better off replacing the red with Sharp's single mode GH0631IA2GC and the blue with a single mode Sharp GH04580A2G, perhaps then he may have a white light source usable for holography.
