Generation circuit and method of nanosecond-level interval multi-laser pulse

The invention discloses a nanosecond-level interval multi-laser pulse generation circuit and method, and belongs to the technical field of laser information, and the nanosecond-level interval multi-laser pulse generation circuit comprises a pulse triggering and interval control circuit 1, a nanosecond-level single pulse generation circuit, a multi-pulse generation circuit and an LD drive circuit. The pulse trigger and interval control circuit sends an interval control signal to the multi-pulse generation circuit, the pulse trigger and interval control circuit sends a trigger signal to the nanosecond-level single-pulse generation circuit, and the trigger signal has transmission delay in the nanosecond-level single-pulse generation circuit so as to generate a nanosecond-level single-pulse signal; a nanosecond-level monopulse signal enters the multi-pulse generation circuit, and a string of continuous interval coded multi-pulse signals is obtained after the nanosecond-level monopulse signal passes through the en
