I make lasers using a regular plastic box, not a flashlight housing. My first laser died because of a bad construction - the switch contacts accidentally touched the heatsink of LM317...So, when building a new laser, I put an isolation tape on switch contacts, just to be sure it will never...

I have tried to mix 405nm and 650nm and I got magneta color. But it was just pointing two lasers at the same place.

Yes he sent me some pictures, but these are not pictures of the stuff I will get, but the same kind of laser head and goggles. He says his camera is broken, so I am waiting until he gets some camera to take a photo of my stuff.

Hi guys, it seems like I am getting Nd:YAG head from some guy from Germany. He sent me the photo, it looks like SSY head, but he said it is german laser and it may have a power of 3MW. I am also getting goggles, a KTP crystal and everything I will need to make it work from him. It all will cost...

It is very possible that my brother will travel to the USA next week. Is there any way to get some SSY-1 (or some other) head to the Slovakia without a risk? EDIT: My brother will not go anywhere :( So I am still searching for a worldwide shipping.

I found these rods as soon as they appeared, before you put the links here. But I don't know how to make a ruby laser, that's why I was asking for a complete laser head. Even if I managed to make a laser head, I know nothing about pulse forming networks. That large rod looks really good, but...

No, I have not...but I'm not loosing my hope and I keep searching and waiting for someone to respond :)

He sold it :(

thanks for the link, I know $300 is not very much for such a laser, but I am sure I can pay more, if it is not enough for someone :)

Hi, I want to buy a ruby laser head (as the title says). I want it good and fully functional, so that I will not have to buy anything else to make it work (ruby rod, flash lamp, mirrors, pulse forming network, etc.). I am offering $300 for it. If you are interested, send me a PM. :yh:

That looks great, I will ask him about it :)

Ok, thank you for your help. I will try to find something.

A non-working laser head is a good option, but I would need to know what exactly I have to buy to make it functional. Could you please find some flashlamp for ->THAT-> laser head and a power source for that lamp? Thanks.

So it is illegal to export ragefinder lasers? Well, this is a disappointment. That laser head from your link looks good, but it has no flashlamp, and I have no idea what flashlamp I have to use to make it working. Also, I will need a power supply (PFN and HV circuit, as you wrote). Thanks, I...

Thanks for a reply. Yes, I also think a laser head would be the best for me. But where can I get one? This looks good, and the price is also nice:->LINK<- But these are only available for USA customers, and I am from Europe. The pulses are very short, but it is better than nothing. They also...

Hi all, I would like some info about these lasers. The power of laser I want should be several kilowatts, and pulse duration more than 1ms. I know about some SSY-1 laser head sold on ebay, but they don't ship it out of USA, and pulse lasts only few nanoseconds (if I read right). Can someone tell...

geohal: That sounds good, I will try it :)

Thanks for reply. I am thinking about using my 18V 3A transformer, could it handle the diode? Also, it is not filtered, nor stabilised. If I make a good circuit, can I power the diode with this? Also, I would like to know how to make a high-power dummy diode. And is there LM317 that will not...

Thanks for reply. I have decided to build a driver first. I tried to search, but I did not find anything useful for me...Is there some good schematic? As I said, it doesn't have to be powered by a battery. Also, what does "multimode" mean? What are "modes" of these diodes? And where can I get...

billg519: Thanks for answer, you helped me :)...so, I think I will buy some good Anti-IR goggles first, and I will start building a laser after that...I don't need any complex battery powered driver, I would be also very happy with a lab-style laser, which also means the housing for a diode...
