  • In order to realize the laser energy attenuation, a cascade three-set disc attenuator was proposed to achieve wide range of attenuation of laser energy. In the attenuation system, exact rotation of attenuation plates was achieved with the stepper motor driven by the pulse generated by the STM32 timer and with the position decided by the Hall sensor. The opto-mecahanical parts, motor driver and rotation control mechanism were analyzed. The experimental results show that attenuation range is 0%~97.51%. Reliability and repeatability of the system are verified. The results are helpful for high power laser attenuation.
