How strong is DVD laser?
The higher the writing speed, the less time a laser has to heat a point on the media, thus its power has to increase proportionally. DVD burners’ lasers often peak at about 200 mW, either in continuous wave and pulses, although some have been driven up to 400 mW before the diode fails.
