put in some 3 volt li-ion non rechargeables burns great lights matches with ease i ordered two lets see when second one comes in if its the same kinda power oh and I ordered cr-2 batteries and charger Imessed up and ordered cr123a should have read a little closer on what battery it took
Finally got it from the PO the other day.
Very impressive for low cost!
I had to pony up the big $$ for the batts at Walgreens since DX just now shipped my rechargables and charger.
Burns great and very bright!
Hey i found out the exact wavelength of it, it seems to be just a normal Dvd diode.

I received this laser this afternoon (~2:02pm PDT 03-19-08), and I wasted no time in running it through my spectrometer.
Wavelength is 662nm, and the spectral line half width is just ~1.5nm - quite narrow for a diode laser.
Okay let me put this another another way. These lasers cannot be pot-modded for higher output. I was able to successfully lower the power roughly 10mW on each laser. There is also some point on the pot (right around where it shuts off) where the laser will operate around 1-25mW. After that I was just trying to get the lasers back to where they were to begin with.
I received mine yesterday ;D.Unfortunately it was faulty. :'(The switch is not contact the battery pole but hey i was easily fix this.
The laser is very good for burning when you focus the beam but compare it with my 100mw red it didnt look much brighter!one could say its the same bright as my 100mw.Compare it with a 50mw green the green one look far more impressive at night as the beam is much more visible.
So this is very good for burning because of the adgustable lens.Anyone know if the diode is from a dvd-r?
Oic.. i ordered 18/3.. the status now says "Processing - Contact us for the latest updates" but there is also a 2nd shipment for the order (ordered multiple items), so i'm a bit curious if they actually sent something off now
