The simulation method and test method of high power narrow pulse laser diode driver are introduced. The laser driver principle function is verified with Energy-storage method in multisim. Based on the theories of power integrity and signal integrity, the core device diagram is simulated with IBIS models or SPICE models of these devices. Finally, the test method of peak power and average power of output light pulse is expound. The final test results show that the functional simulation and the back-end simulation coincide with the design parameters of the current and pulse.
