A new design on high frequency amplitude modulation of laser diode is proposed.The circuits which can produce high precision modulation signal is designed based on direct digital synthesizer (DDS),the circuits can also produce local oscillator signals at the same time. The whole design can implement the amplitude modulation of laser diode at the frequency of 150kHz,15MHz,150MHz with high stability and perform the swift switch between the different frequencies,which pave the way for high precision and wide range length measurement.
