Abstract: In order to meet the needs of variable pulse width,frequency and power for laser fuze,a model of the LD driver circuit is built up based on its principle.By using monostable multivibrators to provide the trigger signal,and using the double MOS driver to drive the LD,a variable high power LD driver circuit,which can meet the requirement of pulse width,frequency and power of laser fuze,is designed through a lot of experiments,emulation and comparison.
