The invention discloses a picosecond pulse generating circuit for a semiconductor laser, which comprises a trigger signal module and a CMOS pulse generating module, wherein the trigger signal module is connected with the CMOS pulse generating module; and the CMOS pulse generating module generates pulse output. A short pulse is generated by using the competing relationship between AND gate input and output. The amplitude and the pulse width of the pulse can be controlled by adjusting the bias voltage of a varactor and an MOSFET. Electrical pulse signals with the pulse width in a range of 80ps to 270ns and the amplitude up to 1.8 V can be generated. The picosecond pulse generating circuit disclosed in the invention can be conveniently applied to drive of the semiconductor laser.
