well they got back to me but it's been like 4 days. oh well guess i'm just impatient

so what do i do if they appear to be ignoring my emails...?

crap well the driver broke or something because the button is stuck and it no longer works. i will be sending it back.

yes actually i am going to as something broke in it just now so the button remains recessed and not on. maybe that was the source of the fluctuation...well it was nice while it lasted.

It is definitely stuck it TEM:01 but this doesn't bother me because divergence is great and it appears nearly as bright as my brothers 150mW green pointer - at times it appears AS bright. It seems stable so I will not return it until it proves otherwise. I will end this tread here I guess...

well this is what i figured out: the tailcap threads are painted silver (its actually copper). the paint was interfering with the electrical connectivity. I used sandpaper and scuffed it so that copper was showing through and it seems to be working great now. However - it is definitely stuck it...

nope. the spot stays the same and when you look at it you cant tell that there are "two" beams (it's too bright anyway).

lol that's kinda funny because i thought about doing that because together my rechargeables are about 1-1.5 mm shorter that duracell alkalines. i'll try it and see how it works out.

ok that is helpful. thank you. How about this: My brand new 2010 75mW Green pointer acts strangely. Sometimes when I turn it on the spot will change brightness and go very dim and then bright again and then maybe it will turn off altogether and not light up again until I take the batteries out...

As I understand it, green lasers use an 808nm IR diode to shine through grin lenses and two crystals which double the frequency of the beam to produce +/-532nm and then through an optical cavity and eventually to a collimator lens. HOWEVER, I have a green laser module which is composed of an...

it burns plastic wrappers easily with a lens. without a lens it will sting my lips after a few seconds and poke holes in wrappers.

as far is the IR filter is concerned - i would get it unfiltered because you said you want it for burning. It will be more powerful without one due to the IR light that the beam will carry with it. Since it will be very powerful anyway you already know the dangers of shining it at people or...

ok, i will ask them. the beam appears to be an oval but when you look at it in smoke there is a distinct separation in the beam that makes it actually 2 separate beams, side by side. i estimate the beam to be 2 mm x 1 mm. Burning ability isn't what matters to me so much as claimed power output...

I bought a 2010 SKYlasers 75mW Green laser pointer with an IR filter and supposedly the output power is >/= 75mW. The problem I have is that it will just barely poke holes in trash bags and make a tiny puff of smoke on vinyl but I have read other threads about people with 40mW non-IR-filtered...
