    Why is green expensive?

    Hey guys excuse my ignorance here, I am shopping for a new laser. I have a DIY 405nm, and I will probably end up getting a 450nm from the laser pointer store. But while browsing online and seeing the prices for high powered 520nm it just got me thinking why? Why is green so much more expensive...

    The difference in diodes.

    So I had some dvd burner drives that have a class 3b laser sticker on them. The motors are out in them so I decided to crack one open. This is the diode that was in it. Why does it look so different than all the ones you see on this site. Is it possible to use this diode? Why does it have four...

    TO build or to BUY?

    So I am wanting an ~1 watt blue 450nm. I can not figure out if I should buy the stuff to build one or just buy one. If I'm correct I will need the constant current driver board, 1 watt diode, a housing for the diode, and then a sled. Those are the main things at last that are coming to my head...
