DVD laser (just out of curiosity).

"William Sommer****** is a ****ing Ass"
Is a DVD laser orange/amber?
It's (supposedly) red. But there would be nothing wrong
using a shorter wavelength.
Utter bull****.
Wavelength is critical to reading the data from a pressed disk.
A short wavelength is needed to resolve fine detail.
** ROTFL !!
What a ****ing MORON and NUT CASE.
FYI
the pit depth on pressed disks is half a wavelength in each case.
DVD players have both IR and red lasers.

Indeed, Phil. And as I said in my reply to William, Blu Ray players have a
blue one as well ...
Since I almost never find CD/DVD lasers with any kind of part number, I
pretty much skated over the few assorted datasheets I'd found.
I sort of only half-noticed that some of them are dual lasers.
There is an obvious danger - I could be mucking about with a DVD laser
trying to get some light out of it, unaware that the IR section is happily
lasing away!
