ABSTRACT OF THE DISCLOSURE A pulse amplifier suitable for use as the pulse current supply circuit in a semiconductor driving device, which circuit cuts of a pulse top side portion and a pulse base side portion of an input pulse with respect to a mesial point of the input pulse to obtain an output pulse having a desired pulse amplitude in response to a control signal, without varying a pulse width. This may be used with a semiconductor laser driving device using FET's as a positive element in a bias current supply circuit and a pulse current supply circuit, and having compensating circuits for compensating differences in the characteristics of the FET's and a laser diode used in the driving device.
