Abstract | The invention provides a high-speed picosecond pulse laser driving circuit based on a radio frequency triode, which comprises a signal generator, a high-speed level translator, a radio frequency triode Q2 and a DFB laser, and is characterized in that the signal generator generates a narrow pulse signal driven by the laser, the narrow pulse signal is converted into an ECL level through the high-speed level translator, the radio frequency triode Q2 is driven, and the DFB laser is driven by the high-speed level translator. The driving circuit is used for driving the DFB laser to emit light. Compared with a high-speed current source driving chip, the high-speed level converter is more universal and has the cost advantage, in addition, the high-speed current source driving chip needs the DAC to additionally provide one path of output adjusting driving current, the high-speed level converter is not needed, and the high-speed level converter has the cost advantage.
