I've been trying to figure out where to put my so6j 12x for some time now... What's a great < $20 host that someone would be willing to make a massive < $20 heatsink for? I want to push it up to around 700mW output and I want to overkill on the heatsink - if this is practical... I've...

Is there any <$100 solution to making these 300mW Mitsubishi 635nm diodes have a better dot / longer distance? I've got a DTR 635 w/flex, in a Moh host and glass lens - and the beam specs are purdy bad. I love the color, it's all part of my learning curve where I buy everything I can afford and...

Hi again, I am interested in getting a cooling device for cooling lab style projects, like the one rhd uses in the "Re: It is Here.!!!!! 300mW "635nm" Mitsubishi..... " thread. (Hope that link works) I was going to PM rhd for some information on this subject then thought "why not make a thread...

Is there a decent source for buying 12x Blu Ray Diodes? I'm looking to buy a 405 nm diode for a home made host and/or buy something already made above 300mW. I'm done tinkering with PHR-803t's... I found a 10x Diode on Ebay for $51 - in a BDR-S06J Sled, but it's in China. There's a 12x diode...

This was giong to be sort of a review of my new 200mW Transformable 532nm laser from O-Like. But instead, it's a "I wish I had more power / the foresight to buy the bigger laser the first time" / (& I love O-Like thread). I love the thing, but it's only 179mW unfiltered and 130mW filtered...

Back storey - I live in the woods. Because of how tall the trees are around my house It gets very dark at night. It's Perfect for shining lasers on and around the trees, and with some dust from my gravel driveway the beams are that much more breath taking *cough*. So what's the problem? Well...

Just when I thought I knew how to spot a scammer, I let my guard down. On Ebay there's a guy, thelaserland who is selling modules he's advertizing as being very powerful. Even though the description is a little wonky, he assured me that they were what I was looking for. And that is where I...

I'm figuring out how long I can safely run my diode with a solid 1" Diameter aluminum heat sink, and while I'm figuring all this out I'm looking for a good battery pack option that may be better than what I'm using. My driver circuit is the typical LM317 based one, powering a 445nm (A-140)...

I'm trying to shake off my ignorance, and have been enlightened somewhat by the members of this forum and I am so thankful that I've donated and will try to be a monthly donor. I have discovered that many people seem satisfied with O-Like's products and there are two that have caught my eye...

With my recent (re)discovery of lasers and even more recent buying binge - I am constantly thinking of fun things to do with lasers and I think I found one. Building a water proof laser... Has anyone done this? What kind of sealants/glue/outer casing w/orings/etc were used? I just purchased...

I hope this is the right forum to post this in, As a relative New-B I'm trying to minimize the risks, but one I had to take was to buy a Green laser from Price Angels. I saw on the forum somewhere people were talking about Price Angles being legit, but I couldn't tell if they were "real...

Hey ! I've really been enjoying the hobby, building hosts & drivers, lurking on the forum reading much of the great information that has been shared. But I wonder if the drivers I am building with the LM 317 w/ cap & diode for protection and tested with a dummy load are as safe to use as the 1...

Hey, I've been lurking for about a month (low duty cycle) and I can tell I'm going to love this place. I actually have an old Helium Neon laser that was given to me in 1983, and I had many years of fun with it...putting on shows for my friends. Then it was stolen in 1999. A few years ago I...
