Design of pulse laser detection circuit is very important in the laser applications, according to the characteristics of the pulse laser, the design of the pulse laser detection circuit is studied from three aspects which are the detection capability, response time and stability. Three main parts of the photoelectric detection system are discussed, which are the photoelectric detector, photoelectric conversion circuit and detector bias circuit. The selection of the photoelectric detector, photoelectric conversion characteristics of the circuit with resistance and photoelectric conversion characteristics of the circuit with transconductance amplifier are analyzed, which offers the reference to the design of the laser detection system.
