Abstract
A semiconductor laser drive apparatus having a semiconductor laser source (LD) for generating a laser light; a switching means (Q2) for supplying the semiconductor laser source (LD) with a first modulated signal (S2) for driving the semiconductor laser source (LD) on the basis of a second modulated signal (S1); a current source (6) for supplying the switching means (Q2) with a current for producing the first modulated signal (S2) in the switching means (Q2); and a bias adjust means (VR) for adjusting a bias direct-current to be added to the first modulated signal (S2).
