Build your own. Not illegal to own a billion watt ( if you could fit it in a handheld) handheld in the usa. It is however illegal to use them irresponsibly. It is also illegal to import them with a sticker not showing their true class. One of the things I like about the more shady china and...

I like really fat straight beams in the 1000mw-2000mw range and spend way to much money on laser stuff... ;);). Old projection screen tv's have lens that help to make some huge beams. I also like 100% duty cycle stuff that plugs into the wall the best.... ;);) We have laws here on power and...

I've started using all the modules and extra diodes I bought, to make a laser show box. I have plenty of little dc motors around. Already figured out how to make some huge freaking beams when I was playing with Nichia 08's.

Not that I won't buy them, just why are they so much? A nubm08 brand new cost me $20 bucks. They are the wrong color for what I want though. I have my own housings for my diodes, bought a lot of 200 for $110 bucks from my awesome supplier. I'm not sure everyone gets the deals I get though...

But how long will it last overdriven that hard without a Tec system? I'm housing them in smaller modules for this project and only using 33mm fans for active cooling. More than enough for the greens and red's I have in the housing box. I haven't overdriven any of those, they have more than...

I'm not really much of a burner. Yeah it's cool for like 10 seconds, for me. I like fat collimated beams that go on forever, the best. I'll have to check out 488nm. I tend to just buy a bunch of whatever I like that I see. Slowly building a very large and mostly un needed laser pen collection...

Oh I read up in here about a year before ever joining, I seen a lot of drama and can only imagine what got deleted. I've noticed some very high horse's with people that don't really have a clue what they are doing, on their backs. I stay out of that fishing hole. I may have to take a peek in...

I'm an addict for shiny thing. Motors, my pet pig, and laser beams ftw!! I've spent a lot of money on laser stuff in the year I've been messing with lasers. Few grand in just the last 2 months!!! You know when you are addicted to lasers, you'll never afford to be a drug addict, lol.

won't you come and wash away the rain, black hole sun, won't ya come, won't ya come, black hole sun............ Hi there. I'm a new guy here too. Sadly I'm north of the dixie line in little Texas. I like lasers, my pet pig, and short walks to the fridge. While those blue pens are cool ( I have...

Did everyone die?

It's a $10 pen, I wasn't even expecting the output it has. Very pleased it is not >1mw like the sticker says. lol. I can actually get it to burn pretty nice when I use a magnifying glass to focus the beam even tighter. I'm actually watching it right now and the beam is steady ( with the tiny 1/3...

I've now added a 515nm-520nm fat beam to my collection. SO SWEET!

I just earned that privi a few minutes ago. I'll get some up tomorrow night. It's the crazest pen I ever seen. Is there a way to up load a video? I could show the strange morph it does too.

I engrave with my most expensive lasers. Whole reason I found this place. Needed to find a part to build my own high end laser. While I didn't want to spend $500 on one single laser module, so I spent $2400 reengineering my machine. lol. I have 12 modules of varying wave size, it is now TEC...

I love the greens too. 532nm is really bright too, my fav is 510-515nm though. Cyan lasers are the bee's knee's too. So many bright colors. 532nm, really bright green. I have a few of them. One is 50mw and it will leave a spot on a cloud 10 miles or more up. I have a few at 100mw-150mw, even...

So I recently purchased a laser from a seedy dealer on eBay, the famous Chinese lasers!!! Now me personally am always glad when they say " >1mw " and I get a pen at 250mw or so. I've noticed it takes a minimum of 100mw of any color really, some need a few more mw, but an average, to get a burn...

They still make them, or you could make your own. if you make 'em, I might want one. lol

Back when a cars manual showed you how to adjust the valves and tighten the timing chain. Now days they tell you not to drink the fluid in the radiator or battery. I miss the days when people used their grey fat.

Why are 405nm diodes 100mw and above so freaking expensive? I can find 20mw-50mw all day long for around a dollar, or two. That's new and use. Just scored 20 pcs of 405nm at 20mw for 8 bucks. I spend a lot of money with a certain surplus laser store, and they return the favor by sometimes giving...

I am now the proud owner of a 200mw-250mw( 250mw driver, cranked all the way up, so maybe a little more or less, don't have an lpm yet) 635nm. It's like a baby little tiny burner.
