    摘要： A semiconductor laser driving apparatus wherein an irradiating energy of a semiconductor laser is adjusetd multi-stepwise by varying the irradiating time within the maximum irradiating time while maintaining at a constant value the optical output when the irradiating energy is lower than a predetermined value, whereas the irradiating energy is adjusted multi-stepwise by increasing the optical output more than the constant value while fixing the irradiating time to the maximum irradiating time when the irradiating energy is higher than the predetermined value. A semiconductor laser driving apparatus having a plurality of current generation devices whose current generation is controlled in accordance with input pulse signals, a semiconductor laser connected in series with parallel connection terminals of these current generation devices, and current control device for adjusting a supply current to the semiconductor laser by controlling the pulse widths of the input pulse signals to the plurality of current generation devices, respectively.
