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.

* Total output power measured at the aperture of the laser.
** According to IEC 60825-1 regulations, laser power is measured by 7 mm aperture stop at the position of 10cm.
*** X meaning focus distance at X meters and it will generate a thinnest laser line at that distance.
Ex: VLM-520-75 LPO-2, it will generate a thinnest laser line at 2 meters distance.
**** Laser Line Accuracy:
***** Operation temperature 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.
