I always assumed that at any given voltage the diode would essentially act almost like a short circuit and try to pull as many amps through itself as it could, and that this was the reason that CC drivers were needed. I find it hard to believe that any semiconducting device can have no voltage...

Those are very nice units but they would almost certainly be confiscated by customs as they exceed 1 mW. They have become quite proficient at finding them (presumably by x-ray). Then again at roughly $200 each I could take a chance twice and probably still be better off than I've been with my...

So a while ago I purchased one of DTR's 1.75 watt A-140 based lasers pre-assembled to resemble a lab style laser. However I made the foolish mistake of assuming that this meant it could be left running indefinitely (diode was mounted in heatsink and was air cooled) but evedently I was wrong I...

I started ordering parts thinking that I would have no trouble setting it up, and perhaps I would not have, but I later realised that a decent pair of safety glasses would set me back perhaps $300, doubling the total project cost at that point. I then realised I'd already spent a few hundred on...

Please note: Australian buyers only, sorry no international shipping. Big Sky Er:YAG pulse laser head + 2200 w PSU + Aerovox HV capacitor PARTS ONLY | eBay So I bit off more than I could chew starting a Er:YAG pulse laser project, both in terms of my lacking technical skills and cost involved...

This is true for the importation of handheld laser pointers into the country and is true in SOME states. However there are some states in Australia where the possession of lasers is not controlled in any way. Of course they must be used with care and consideration of others (if you shine it at...

Hi everyone, I'm a scientist from an Australian university however my area of expertise is not directly related to lasers. My interest in lasers is mostly a (expensive) hobby. I live in one of the Australian states that does not have outrageous 'anti-laser laws'. I've had an interest in lasers...
