Some of you are aware of thes cool little lasers, after many years of trying to chase down a decent source, I’ve finally found some! These are brand new unused units capable of 100mw+( with active cooling no doubt), but set at 75mw will remain stable and needs only passive cooling ( attached to a heat sink) to run stable for hours. I’m offering a few diode assemblies to the forum members.
I’m selling these at $75 each includes USA shipping and shipping cost only, to outside the US. Easily run with 80ma for the heater and 500-800 ma for the diode. Your diode will come tested and pigtailed w ESD protection...
If you would like a dual driver ($25), I can shipp this along w your diode at no addional cost...to help your build I have started an FB group “laser hacker” and will also post here to answer any questions...anyone interested send me a pm and I’ll send you a PayPal link.

Here s video I did to check the coherence length of the amazing lasers ...

I can easily see a meter int this hologram !

Great work you've done here, I saw some of the holograms Travis made with these lasers and they were fantastic.

Price point can't be beat. Hope some prospective holographers find these well!

I’ve sent out 5 kits , all seem to have made safely, now we need to see some holograms! I’m currently sending two complete built units to Phil so he and Sam can test, I think due to its dfb( hologram!) IR laser’s narrow frenquincy provides this laser w so many “happy zones”(SLM). Plus the ability to run it remotely for hours
On a phone charger battery !

wow post the red one its clean and bright, I so want one, just got you green kit hoping to make some test very soon, this is truly brake through, in getting lasers out there with out bankrupting the student that wants to learn holography and also do 2 color at a reasonable price, Go Dave, Go

Thanks Danny! Sure would like to see a hologram made
by you “kit” holders... here’s a picture of of a hologram
I made last night using the red laser (650nM) harvested from the same pico light engine.
