Feedback mirror for partial splitting of 532nm light in low-power green laser module
Feedback mirror
Explanation: For the green laser module, a low-power type, partial splitting is performed on 532nm light, and the split light path is used as an induction chip as a feedback signal to adjust the stability of the laser power output.
