Re: Even w/ proper driver circuit my laser diode f pocketfluff - If Im still getting a spike using a decent quality benchtop PSU -> driver -> diode then all hope is lost and even batteries won't help. I do think the issue is heat given the feedback Ive recieved here. I thought the Aixis housing...

Re: Even w/ proper driver circuit my laser diode f Is it okay/recommended for me to place the Aixis housing into a heat sink? Or do I need to place the diode itself into a heatsink? Thx

Re: Even w/ proper driver circuit my laser diode f Thanks I will search for that. This is what I built (I have under 20 posts so I cannot post links. Just take out all the spaces and to make the URL) ww. instructables. com /id/ Laser-cutter - start - slicing - stuff -for-under-50-dol/ It...

Re: Even w/ proper driver circuit my laser diode f Thanks, very good info!

Re: Even w/ proper driver circuit my laser diode f Ok I can manage that. How much surface area do I need? I need to keep it light so the stepper motors can move the laser smoothy. So the smaller the better but I obviously dont want to have too little like Im at now.

Re: Even w/ proper driver circuit my laser diode f Hmm, Ive read the Aixiz housing acts a good heatsink for these? Am I wrong? What are my options for heatsinks? Buy them anywhere? or do I have to make one? Thanks for all the replies

Re: Even w/ proper driver circuit my laser diode f Ahh ok. With the second diode, I had it one for maybe 2 sessions of 15 minutes within 1 hour. Then today I had a maybe 3 5 minute sessions with a 5 minute break inbetween and then the last two where about 10 minutes with about 20 minutes...

Re: Even w/ proper driver circuit my laser diode f What do you mean by Duty Cycle? Im using the Aixiz housing for a heatsink and then there is a metal clamp that is holding the Aixis housing so that it acting as a heatsink too.

wtf Im so lost on this. I bought a sony diode pre-installed in an Aixiz module. I ran it straight from a benchtop DC power supply @ 2.9v 220mA That one fried. So I buy another This time I also purchase the Laser Diode Driver KIT (LM317T based) and a Sony Diode pre-installed in a Aixiz module...

Re: Did I fry my first laser or is something wrong Here is how it was mounted. I built a stencil cutter based on these specs (). I dont think the mounting caused it to fry, its right in the open, held by a metal arm. 24.110.142.91/images/laser005. jpg 24.110.142.91/images/laser006. jpg...

Re: Did I fry my first laser or is something wrong Hmmm interesting. So did I drive it wrong? Do I need to build one of those driver circuits? I thought having a benchtop DC power supply could take the place of those circuits becuase its so controllable?

Hello - First off Im a laser noob and this is my first project. I bought a Sony DVD-RW diode in a Aixis housing from StoneTek. Im driving it with a bench top DC power supply 2.9v @ 220Ma The first several days it worked great, bright and focusable, perfect. Last night I go to fire it up, and...

Just ordered a pair tonight!
