Yeah, I'm not expecting great durability out of cheap lasers. All I was looking for is a cheap way to test the idea. If I knew what the minimum wattage for this was, I would buy several different wavelengths and whichever performed best I would then buy a more powerful one of that wavelength.

Y'all are right, there are better ways to kill weeds. Most herbicides kill the root and all the first go around. The problem is for the organic folks, which is where crazy ideas like laser weeding come from :D And killing just the foliage on a strong weed will not completely kill it. However 2...

Oh, so if I click multiquote on all the people I am quoting it will quote them all in one? Also, Is there a way to combine them now? Thanks.

Being the cheapskate that I am, I found this laser that's for an engraving machine that's seems like a pretty good deal. It's 1000mW, 405nm and says the input voltage is 4.5-5v. LINK: 1000mW 405nm Engraving Machine Cutter Engraver Laser Head With Violet Light US | eBay Does this likely come...

Thanks for the warm welcome all! I'll try to mind my manners and see what information I can glean from you folks. I had to laugh at this one: Quote: Posted by RA_pierce "Welcome. Sounds like an interesting project. How will your automated system discriminate weeds from plants? I imagine...

Hello all, I am working on a project that would use lasers in an automated system to control weeds around plants, like in a green house. As a little background, I have played around with concentrating sunlight some. Which has some similarities but is different than lasers of course. I do not...
