After being off for a long time, I was looking into getting another laser but I'd like to figure out how bright a 445 will be to say, a 532. The calculator here isn't up anymore though. Is there anything similar?

Lets say you had a diode mounted to a heatsink that was 100% efficient in removing excess heat from the diode. What else limits the amount of current that you put through?

So a few weeks ago I ordered one of those ebay "5 mW" 405's knowing that it would be overpowered, but what I got is more than I expected. I dont have a LPM, but how many mw's do you think it is if I can see the beam in my room with the lights on? It would have to be at least 100+mW right?

At my cabin we have a stealth cam that is motion activated and takes 9 pictures automatically when it is triggered. A little while ago, we went up to check it and we got these pictures UFO pictures by WOLFHUNTER9154 - Photobucket (there's some doubles in there.) There is also a picture that I...

So I finally finished my Kryton groove LPC-826 build! (Well actually, I finished it a while ago but I'm finally posting it) It is running with a Rckstr running at max current which I think is around 430 mA. I also purchased one of those "broken" 473's on ebay. It was easily fixed by switching...

I bought one of these Non-Functioning 473 nm Blue Laser, DPSS, BWB-10-OEM - eBay (item 320715493145 end time Aug-01-11 10:34:54 PDT) to play around with and learn about the insides of it. I turned it on and for the first 1-2 seconds, it is bight, but then it began to dim to very low levels (less...

Today, I finally finished my red build. After killing 2 LPC's I remembered that I had an old DVD burner. I dissected it and got to the sled. extracting it... That was a different story. While trying to get it out of the heatsink, the can was partially crushed (the aperture hole is now an oval)...

Earlier today, My LOC was working fine, but underpowered by an 18650 rckstr. I got some cr123's today and set the driver to 370 mA and connected to diode to it again (after I shorted the cap) and Bam! it was LED. It there anything I could do to prevent this from happening again (I was grounded)...

I broke my flexdrive a while ago, and as I was sitting here with no lasers, I remembered that I had my rkcstr drivers. But then I remembered that I needed to have a few volts over what the diode needed. So my question is, What batteries will work to power a 815 @ 300 mA in a groove?

I was working on my phr build today and i was using a kryton groove (kind of overkill). The tail switch didn't work but I didn't know that yet. I took everything out and tested it. I tested the circuit i set up and it powered the diode. Then I tested the tail switch and discovered the problem...

I'm not sure what happened to the switch I had but it wont let any power through it. If anybody has one that they would like to sell/knows where to buy one it would be appreciated.

I've been off the forums for a while so I have been "out of the loop". Can someone explain 445 nm like what they are used un an why they are so cheap? -wolf

I was wondering today what color do you get if you combine red and violet? Pictures would be appreciated.

Hello, I signed up a couple of weeks ago and I forgot to do this so here it goes. My name is Matt and I'm from new york (Buffalo) and I'm 14 .I was doing one of my random searches on Google and I found this magnificent stash of information. I Like Lasers (obviously) and Computers. I actually...

To start off I am just pricing these it is likely that I will buy but I might not. I am in need of 2 of the lens dichro's from the psc laser sled because I want to make this http://www.rog8811.com/lowcostyellowpointer.htm

I recently purchaced a 150 mW laser doide and driver parts and it was working fine for a day but today I chenged the battery and when I did that the diode is dim now. (it was a brand new battery) any ideas?
