Laser Printers

[Me]

Can anyone tell me what class lasers are used in laser printers. I'd also
like to know what class lasers are used in cd-au, cd-rw, laser scanners,
laser speed guns and wafer production.

Thanks.

It's research for school.

Laserprinters usualy have a Class IIIb (3b) laser that is nominally a 5
milliwatt gallium arsenide laser operating in the wavelength region of
770-795 nanometers
