Semiconductor laser control system

The utility model relates to the field of semiconductor laser control, in particular to a semiconductor laser control system which can provide three paths of voltage-controlled voltage source module outputs and four paths of voltage-controlled current source module outputs, has various voltage and current output combinations, and can drive different types of lasers through control of an upper computer. A voltage-controlled voltage source and a voltage-controlled current source in the design are relatively independent, the size and frequency of each path of voltage and current can be independently controlled, the characteristics of continuous voltage and current output, good output synchronism and the like are realized through a specific processing circuit, a microprocessor control module with a high-performance DSP (Digital Signal Processor) operation processor as a core is used, and the voltage and the current can be continuously output through table look-up calculation. The current value of each voltage-con
