For a couple of months now I've been trying to design my first handheld laser and it's been slow. Currently, I have a 445nm 1.8W diode pressed into a small housing and a heatsink which I got both from DTR's laser shop. I'm also using the DTR-3E-B lens since it's the cheapest. I'm don't...
I've been looking for a cheap and strong laser diode or pointer that I can buy. I found this one from SygMall and I want to know if it's actually 2000mW like described. If anyone can help it'll be appreciated.
