Hi everyone, I recently bought the GH04850B2G (488nm) and the GH05030C2LM (505nm) After hooking the 505 diode to my driver according to the specsheet the LD didn't turn on Since I knew that this diode is case positive I just switched the negative feed to the other insulated pin and it worked...

What do you think ? Quantum well/barrier intermixing blue-shift of indium gallium phosphide

Yo guys, Just wanted to show of the builds I've been working on the past few months (consider that waiting for the parts counts as working time too lol) From left to right: First one uses an Oclaro 700mw diode running at 1400ma (~900mw) from an 4x AMC7135 board with an 3 element 650nm coated...

Yo guys, Havent been active in lasers for a few years now and would like to get started again. Im looking for a driver to output ~1A from a single cell. Preferably a cheap one with a spring attached to it already :p So i came across these two: 445 450nm 0 3 1W Laser Diode Drive | eBay...

HI, Alright I am planning a ehgemus build with a jib77 driver. Since these drivers require an input of at least 6v two 3.6v 15266 batteries should do the job. So my question is how long these batteries will last ? The battery says 600mah but i think it is not true. If you need the link of the...

50mw Budgetgadgets Review SHIPPING Shipping took about 15 days from Shanghai to my home , which is pretty quick for China. As nearly every laser you order from china this one was also packed in a big bubble wrap package. I asked the support for a tracking number which was not accurate...

Saw this video on youtube : YouTube - Is Your Luggage Safe from Airport Security? 2W laser ? Looks like an ehgemus host ! What do you think ?

hi why does my new green laser from budgetgadgets produce a few artifacts ? How can i remove them ? pls answer

Searched through the forum and did not find a graph of 445nm diode. Anyone tested this diode and wrote down the ma and mw ?

HI, I may want to build a 445nm laser soon. My soldering is nearly dead so i want to pick up a new one. On ebay, i found a "micro soldering iron" 8W and 450°C heat. Had anybody of you experience with a soldering iron like this ? P.S : Did not know where to put this thread :whistle:

HI, I am wondering why members use 2 flexdrives or microboost drives. And how do I use a microboost drive in a host ?

Is this one really 50mw ? DealExtreme: $19.70 SD-200 50mW 532nm Green Laser Pen Pointer with Strap (1*CR2) Is there any difference between the budgetgadgets version ?

Hi all, I have two 50mw green lasers now. And now i think it is time for a lower powered one. I'm deciding between the DX true 5mw or the true 10mw. So which one would you suggest me ?

HI, Just got my 50mw laser from budgetgadgets. Everything is working fine but the divergence is very bad. The divergence is around 2.5mRad (at infinity) Is there anything i can do to refresh the divergence ? I mean styropyro reviewed this laser a month ago or so and his divergence is great. Thanks

Dealextreme added an new laser to their violets. DealExtreme: $29.10 Focusable 200mW 405nm Burns Match + Money Detector Blue-Violet/Royal Purple Laser Pen (2*CR2) looks like an old dilda style but in violet.
