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.

* This product meets specified certification standards, 21 CFR 1040.10 (United States) and IEC 60825-1 (Europe). Please refer to the final page to see the test report from a nationally recognized testing laboratory, SGS, that shows evidence that this product was tested according to the standard IEC 60825-1. Besides, this product has the Food and Drug Administration (FDA) accession number.
** Operation temperature: it means within this temperature range, the laser spot/line will not be affected to change the spot size/line width. It can still work over this range, but the laser spot size or laser line width will be larger.
*** 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.
