Thanks for the response Immo. Divergence is trivial to incorporate into the model, and the assumption of a perfect vacuum won't significantly change results at these distances. However, you are correct that 5mW of parallel rays, such as those emitted from a laser, will be more dangerous than...

Thanks for the responses everyone! The general consensus seems to be that it is indeed safe from a reasonable distance. I'd like to clarify that the math is there not for the purpose of proving that "it is probably safe to look at laser light from a reasonable distance", but rather as a shitty...

Hi guys, my first multi-watt laser arrived today, a 3W 445nm build by Lifetime17 (which I am very much enjoying, thank you Lifetime17!). I wear my Eagle Pair glasses whenever I operate the laser, but I have read in several threads here that it is safe to view even high-powered lasers when they...

Thanks :D He definitely seems like he knows what he's doing! Safety is the most important thing, I totally get it. I'm glad you guys take it seriously.

Thanks hakzaw1. I apologize, I felt like my question didn't belong here when I posted but I went ahead anyway for some reason. That is my mistake. I updated my account details to reflect my location (Ottawa). :D I got in touch with Lifetime17 (as suggested by GSS) and I think he's gonna hook me...

Thanks GSS! You and everyone else are so helpful, seriously. Your taking time out of your day to help a complete stranger. Anyways, at my price budget, I think 2-2.5W would be an acceptable compromise (though higher is still better haha). Your suggestion to buy a module with driver already set...

Thanks again for your help! I'm hoping to purchase all the parts by monday. This is a link to the driver, and I believe has current adjustment which is good...

Wow, that's a lot of stuff! I don't want to order from DTR unless I order a few components at a time to save on shipping cost. There seems to be plenty of hosts on ebay, are they bad? Also searching TO-5 diode press didn't get me correct results :( I'm gonna keep researching. So far I have this...

Thanks so much!! I have never built a laser before, so I'm not sure what kind of tools I'll need apart from a soldering iron for this. Do you mind helping me make a parts list? You've already recommended a diode and driver, do you have any recommendations for where and what host to get? I really...

Thanks so much everyone for the warm welcome :) I'm from Canada by the way! If you guys say it's cheaper to make my own, then I'll probably take that route. From the looks of DTR's shop (seems to be recommended for parts) though it seems like it will cost much more than buying something like...

Hello everyone. I read it is good to make a post here as a new user, so here I am! :D Lasers are fascinating, I've loved playing with them ever since I got my first 100mw green one. Oh, I also have a question. Perhaps if someone can help me out i'd really appreciate it. I have a budget of...
