    big problems with sharp 185 mW 638 nm diodes

    Hello, I set all my 5,6 mm diodes this way, so that the back of the module touches the bottom of diode to get an additional heat transfer. best regards Edgar

    big problems with sharp 185 mW 638 nm diodes

    Hello, below one photo of the extracted diode and one photo of the second diode. All I could find was the number on the bottom of the diode. Is that new for the sharp diodes? best regards Edgar

    big problems with sharp 185 mW 638 nm diodes

    Hello, I got two 500 mA drivers today from X-.wossee. They are set below 100 mA. I tested the remaining driver with a dummy load, it works fine as usual. I will see what DTR will answer. Maybe it helps to extract the diodes, to see if I got the correct diodes. best regards Edgar

    big problems with sharp 185 mW 638 nm diodes

    Hello, today I got two sharp laser diodes Sharp GH0631IA2G 185mW 638nm Laser Diode from DTR. I pressed one into a 12 mm Copper heatsink from DTR and connected it to a brand new 500 mW driver from X-wossee. Nothing happened! No current, no laser light. After that, I connected the diode...

    WTB: laser diode extractor tools

    Hello, today I made an extractor for 5,6 mm diodes. The extractor will fit to the DTR copper modules. Sorry, that i could not test it, but i will not extract a running diode. But I am sure it will work. best regards Edgar

    WTB: laser diode extractor tools

    Hello Paul, yes I can do it with one adapter and two pushing screws. Until now, I had only dead diodes to push out, that was very easy. Best regards Edgar

    WTB: laser diode extractor tools

    Hello, what kind of extractors are needed. Maybe I make one today for the DTR heat sinks. It will be a brass Adapter that fits the 9*0,5mm threads of the copper heat sink, with an inner thread and a steel press screw. This will work with 3,8mm diodes and 5,6mm diodes, but not with the 9 mm...

    Osram PL530 - Tiny 530nm OPSL

    Hello, don´t get me wrong, the connectors were broken inside, but you could not see that. So it is safer to use massive copper wire. When you have voltage and current, than this is another problem. best regards Edgar

    Osram PL530 - Tiny 530nm OPSL

    Hello Dragonsired, some weaks ago, I tried to get a LM317 Driver running with such an experimental board. It did not work. Than I noticed, that 2 of 4 wire connectors were dead! After using copper wire, everthing works fine. best regards Edgar

    looking for flashlight hosts

    Hello, Mountain Electronics has a lot of things for DIY. But they do not ship to Germany at the moment! So Kaidomain will get my Money. best regards Edgar

    looking for flashlight hosts

    hello, thanks for the info. First I have to buy the Diode and maybe some heatsinks. I will have a look on all the links you sent me. I ordered 3 Convoy S2. But then I noticed, that these are also nice flashlights. So only one ended as a green laser pointer. best regards Edgar

    looking for flashlight hosts

    Hello, the Ultrafire C8 looks good. I also like the look of the Convoy M1 and M2. The next laser will be a medium sized, single mode 638 nm laser. I built a laser with the Oclaro 700 mW Diode, but I don´t like the divergence of this Diode. best regards Edgar

    looking for flashlight hosts

    Hello, I made complete DIY Hosts for my first power lasers. Then i started to use flashlicht hosts. I think the ultrafire 501B hosts are nice. For medium power laser the convoy S2 is fine. Now I am looking for other possible hosts with 18650 batteries. I am also looking for better quality...

    Anyone know whre to buy laser diodes that are 1 nm-100nm?

    Hello, it is possible, but you need a free electron laser, not a Diode laser. I think, this device is not portable. best regards Edgar

    Beam stopper?

    Hello, yes, I tried the black Velvet at distances of 5m ore more with a 1 W green laser. Sure, it is no option for power laser. In this case you risk a burn. I must try the black anodized Aluminium. It should also look nice at my Aluminium heatsinks. Has anybody experience with DIY Aluminium...

    Beam stopper?

    Hello, what do you want?. Do you like to see the focused beam on a target or do you want to absorb all the light on the target? In this case I would suggest to use a black box with black velvet inside and a hole at the target side. best regards Edgar
