I really dont think anyone will sell you a laser build for 77 dollars. Save the rest for a nice build. Your not that far away ;)

And dude, change your avatar, thats just ridiculous....

$77? I doubt it... You can probably manage ~$100. Consider this, the diode itself is $45, a good driver is about $20 ($65 total), you'll need a host kit $20 ($85), and non-acrylic lens (acrylic will ruin the diode!) and module $13 ($97), plus shipping costs ($?). Some members buy parts in mass and are able to sell it for $100 in the end, but going any lower would be a waste of money and time on the builder's part.

I'm dying of laughter due to your avatar! :crackup: But really I don't think you will get one for $77.

Nah. You just need to remove that black thing on the lens. The kryton groove I got off mariomaster was outputting 700-800 mw with an acrylic lens when I got it. I even mentioned "Arent these supposed to melt at over 400mW?"

Actually no, the lens itself will melt with Class IV powers with lower wavelenghts. You really do need glass lens with any blue laser, plastic will melt.

Though the poster was also incorrect, it won't ruin any diodes. It'll just ruin the beam and cost you money for new lens, and waiting time for it to arrive.

Huh. My guessing seems to prove opposite... :eek:
At least know that acrylic is still a bad plan. I should pull out my 445 and some acrylic blocks to see if I can do any damage

IIRC the lowest priced 445nm I've ever seen was $80, it was an "experimental" used laser, with a crappy diode.

Correct me if I'm wrong, but it's not the lens itself that's damaged... rather the plastic lens holder.

Also correct me if I'm wrong, but burning plastic can produce smoke, that can adhere to the diode window, and burn on with time... also ruining the diode.

Yes Please :p
