Abstract
A laser device suppresses the variation of each time-lag so that a distortion of a combined laser output is suppressed. The laser device includes electric current control elements Q, Qconnected in series to a laser diode unit corresponding to respective laser diode units LD, LD, an electric current control circuitthat controls an electric current flow in the laser diode unit by adding a voltage to a control terminal of the electric current control element to turn on the electric current control element, and voltage adjustment circuitscorresponding to the laser diode unit adjusts, individually, every laser diode unit and the voltage that is added to the control terminal of the electric current control element when the laser diode is off.
