Hi Guys,

My laser currently smokes black plastic and shines into the night sky but it couldn't light a match. After more reading, I read that one has to actually wided the diameter of the rear of the AixiZ module lense. I didn't know this before. is there a guide on how much wider we should make this hole??

I also understand that with the small hole that I had earlier, much of the laser would have been reflected back into the chamber. Would this have caused any damage to the LD?

Thanks.

well, to be honest you can just carve out the circle with an exacto knife and whatever you cut out is going to be an improvement. However, you need to be cautious that you don't let the knife hit the lens. If your really good you can just pull the whole back part off. It's hard to do.

Now the increase in hole size is not going to really increase the output power of your laser to allow you to burn white matches. For the most part you need to learn HOW to burn an unsharpied match. You have to stay pretty much right at the bottom of the sulfur in order to do it. You can't just focus it on the center of the sulfur and expect it to happen. I'm makin 180mw lasers all the time and I've yet to put the laser on the center of the sulfur and light it!

Ohhhh so it's not that easy to light a match huh...

Worse still, I was using those big ass 'light anywhere' matches with very glossy big sulphur. Maybe that's why they never lit heheheheh.

Ok I'll try cutting that back part out 1st.

Thx.

Sharpie must be a brand name i think. In the UK we call them permanent markers.

I have no trouble lighting non-sharpied safety (wood) matches with 160ma's. These are the brownish red headed ones but they are more on the red side. I don't need to worry about where the laser is focused on the match.

The white headed paper matches will light with 160ma's provided the beam is focused at the base of the sulfur. But with 250ma's, I can light them too no matter where the beam is focused on the head of the match. But the focus has to be almost perfect, and this is with the match about a foot away from the laser.

My matches have really big and long sulphur which are ver glossy because these are wind and water proof matches... when you strike them the sandpaper scrapes away the gloss and lights the inside. The gloss is basically a water proof coating.

Anyway, I sand papered the tip (big red sulphur) to remove a bit of the gloss and I'm able to light them by focusing the laser on the middle. The match will smoke at first and then the sulphur lights.

Hi DJEEPER,

Yeah I've managed to light matches ever since I cranked the amps up to 260mA and the voltage up to 2.9v :)

Thx.
