Talk:3W Laser

Granted i am in no way an optics expert, but from what I have seen is that you can use low powered lasers for laser cutting/engraving for wood. This is great for prototypes/art, but if you want to cut thick wood, metal, do laser welding, or do powder sintering/melting you need something in the 500W-10KW range.
