What is the life cycle of a blue laser... like the ones used in the blu-ray players... it's for an engineering project. Answered

I can't find anything on the web about it... if i could get some website links... it would be greatly appreciative.

That's research project, not something you can get from a quick answer in here.

Start with how you make Blue lasers ? First take Indium and Gallium metals and form InGaN .......

There's no reason why they couldn't be recycled, but the "guts" are so tiny that it wouldn't be cost effective unless you had millions of them at your disposal, and could extract the grain of sand that constitutes the die.
