I just picked up a 500 mW 635nm customized laser diode module from DTR.

I was really impressed by DTR (https://sites.google.com/site/dtrlpf/). He answered questions promptly. His prices were reasonable. I asked for a custom module (one of his standard 500mW, 635nm modules, but with the current tweaked down a bit) and he was very accommodating. In fact, I send him a paypal payment on Friday and I had the laser in hand and working on Monday. Part of that was that the mail cooperated, but most of the credit goes to DTR who modified the module within a few hours of the order and rushed it into the mail. He's someone I'll do business with again and would highly recommend to others.

His knowledge was solid. I'm an optical engineer by profession and someone who did early research in laser diodes -- and I can attest to the fact that he really knows his technology.

He really does deliver the power he says. That being said, I'll remind all of us, to quote, "you'll shoot your eye out, kid!" These lasers are well above the eye-safe level if used stupidly. Don't use them stupidly. They really will burn your eye out faster than you can blink. And the damage will be permanent. Know what you're doing when you buy something like this. The burden of safety is on the integrator - and you're buying these to integrate into a system, taking all necessary steps to make sure that they're safe. Google ANSI Z136.1 and follow the directions. Your eyes will thank you. *stepping off my soap box*

If you're looking for a high performance, solidly built product, at a reasonable price, and delivered quickly, go to DTR. You'll be happy you did.

Yep DTR is great. The only problem with DTR is he has way more diodes than I have money to buy with. :crackup: I have six more diodes I need, hopefully the end of the month or the middle of next month I can get them :)

Yes I too recommend DTR and the products he sells, always helpful and I am sure he lives either upstairs or downstairs at the local Post Office, always super fast delivery from time of order placement! :)

OK Tmack. Put the soldering iron down. Step away from the bench. Take out the trash. :crackup:

hahaha might be a good idea. i have to swim through bubble wrap to get to my bench.

i have dozens of empty dtr packages, and dozens of hex wrench envelopes from mrcrouse!!!! i started using them instead of toothpicks to apply my thermal paste they are so plentiful.

Mrcrouse is another one like DTR. They both pay attention to detail. We are fortunate to have members of their caliber.
Sounds like you are building some great lasers Tmack ! Keep up the great builds ! :beer:

lol ill build 4-5 in one sitting if i have enough orders.
the worst part now is my little workshop has no air conditioning. by the time the iron is hot im completely soaked.

when you get a good rythem going, and your building a bunch of the same lasers you can really blow through them.
on most the longest part is waiting for the thermal adhesive for the driver heatsink to dry.

the soldering is very quick.

Ordered some copper modules a week ago and they are in my mailbox now, and im in Canada.
