pre-orders/interest for high quality module kits

[sbk]

This just in: it appears it will be possible to have a dual version of this without too much extra cost! The dual setup will be an option when orders are placed. It will contain an extra collimator set and knife edge hardware. Given that the beam width was going to be about 4x2mm, it makes sense to fill it out with another diode internally to give <4x4mm final beam. My measurements show the final beam size at aperture will be 3.5x3.5mm.

What's about the size of the dual? Will it be the same case as the single?
I'm in for 3x single, or eventually 1x single and 2x dual, depending of the size...

And, depending on the progression of the open source TEC driver at the moment of your sale, I will eventually buy only the modules without drivers. Is it a problem?

count me in for 2 if the price is reasonable.

0.7mrad at full angle? Thats better then a KVant or RGB lasersystems. I think you nailed it ! Maybe the collimator from MCcarrot has less losses but with so much blue its not that important.

Congratulations Dr Lava with these results

Also i,m very impressed how quick you came to the result. And since you have plenty of interests you probably make a few bucks too Always nice to fund new projects.

The lenses I will be using will be broadband type 'A' AR coated, also <1% loss typ at this wavelength.

Edison, thanks, it hasn't been that quick of a project. I've been reasearching and testing for more than a month now on lensing combinations. Also spent hundreds of $ buying test lenses.

I notice a few people (mostly people that run laser sales stores) are asking for the lens details. I'll be happy to give them out once the research cost has been taken care of. If anyone of these people wants to chip in to defray that research cost, that would be very helpful, and the details could be released sooner!

Still, the 'wow' factor of "OMG, this place has LASERS!" will probably drop like a brick

Depends on where you go. Everywhere I go have lasers permanently.

The thing I've always noticed though is how un-educated audiences are about full colour. Ask your average trance audience and they all ask for green lasers above colour!!! However, thats because most of them haven't seen full colour if thye have, have only seen colour at standard MPE level witht he washed out colours that results and of course when they compare them to green and its brightness, they seem poor in comparison.

As laserists, we all know better.

As for putting people out of business, I don't see why cheap RGB projectors ever will. At the end of the day a projector on full auto is very different to a Live Pro show. A good show will always trump a repetitive auto offering so in the future I think the market will still be there but it will be focused more on quality show production than on arriving with a colour rather than green projector. In the long run, that can only be good for the industry as it will help weed out the poor producers in favour of those who can create something rather special.

Hi Dr

I would also like a dual Kit as well

i think you are gonna be kept busy for the near future ....

all looking very good

many thanks and all the best

Ok, I've taken some photos to show about what to expect. These are taken with full flash at about 150mW.

Emission: 3.5mm H x 1.5mm W

At 40 feet (12.2 m) off of 1 mirror (Laserman 532's cool new micro mount)



At 80 feet (24.4 m) off of 2 mirrors

I would definitely be in for at least 1 dual setup ONLY if these came out soon. I just cant wait to put in some 445

drlava,

Great work in finding a suitable solution to get a decent beam out of these diodes!

I'd likely be interested in one single diode kit or one dual diode kit depending on the increased cost and size of the dual kit.

As you said the dual kit will use two beams knife edged side by side to achieve an <4mm square beam, do you have an idea about the possibility of a quad kit using two sets of knife edged beams combined with a PBS cube, perhaps with a beam profile similar to the attached image? (Original image courtesy of mccarrot in this post.) It seems like such a setup would provide similar beam specs as the dual kit with quite an increase in power.

Also, I suppose if one used two or more drivers, say one to drive the horizontally polarized diodes and another to drive the vertically polarized diodes, one could use the separate modulation inputs to select between two power levels and achieve finer control over the output power in the 0-2W range.

Although certainly overkill for the projector I plan on building sometime in the future, three to four watts of 445nm in about a 4mm square beam at about 1mRad diagonal divergence would be very impressive. Perhaps one could use a telescope to decrease the beam size. If I'm doing my calculations right and assuming a 4mm square initial beam with 0.7mRad square divergence, a telescope could provide a 2.4mm square beam at about 1.65mRad diagonal divergence and would be equivalent to about a 3.4mm diameter beam. It seems that'd be a good match for most of the higher power Chinese green DPSS units out there.

I'm definitely looking forward to learning more about these kits. Thanks for all the research efforts!

So how long are we looking at before such a kit becomes available? And as a few people including myself have already asked, can we buy the optics separately if we are designing something that doesn't require other hardware? Likely price on optics alone?
