Semiconductor laser output control circuit |
摘要 |
A semiconductor laser output control apparatus for controlling a drive current to be supplied to a semiconductor laser which is turned on and off so as to maintain a light output from the semiconductor laser at constant. At the rising edge when the semiconductor laser is turned on, constant current supplied from a constant current source to the semiconductor laser is corrected by correction current.
