Abstract:
Disclosed is a semiconductor laser driving unit that outputs a driving current for driving a semiconductor laser. A value of a correction current is set in such a manner as to determine a rising characteristic and/or a falling characteristic of an output of the driving current in accordance with a value of the driving current.
