Research On Embed Intelligent Semiconductor Laser Power Supply

Because the semiconductor laser is widely used in the various fields, the driving power supply is more and more attention. This paper takes STM32as the semiconductor laser power supply intelligent microprocessor control system, focuses on how to stabilize the optical power control and constant temperature control, through precise control, greatly improves the stability of semiconductor laser work, prolong the service life.In this paper, firstly, the working principle of semiconductor laser damage analysis of mechanism, characteristics and usage requirements. In accordance with the requirements of the technical, taking STM32F103VET6as the core controller, each part of the design of the corresponding hardware circuit, the constant temperature control part, a software processing algorithm corresponding. According to the design scheme, the hardware debug.
