Does any cd/dvd rom have one of those?For engraving you need high end Class 3B's or preferably Class 4. But there is more to engraving than just power. Beam specs are also important. Single mode 405's are very good visible diodes for engraving as they have a nice clean spot and very good power. Multimode 445/450's are also commonly used as they have higher power to counteract for the wider spot.
Nope - CD/DVD laser diodes are usually low end class 3B infrared diodes (e.g. under 150mw @ 780nm).Does any cd/dvd rom have one of those?
