About APC (automatic power control) circuit:
The Laser output power must be stable especially in safety reason.
But the Laser power is related to the Junction Temperature (Tj) of the LD. It means that as the different Tj, the Laser power will be increased or decreased.
An APC (automatic power control) circuit is used to compensate the varying Laser output power to constant.
As shown in the picture, The principle of the APC circuit is monitoring portion of the laser light from the LD by the built-in PD and real-time feedback to control the laser output power constant and safety.

** Laser module housing is an electrical positive surface, it is imperative that contact between the laser module and the machine be avoided. This is to prevent damage from the machine electrical leakage. Surge protected power supply to the laser module is strongly recommended.
