Two principles have been proposed for the active monitoring method, adopted to the AR Coating semiconductor lasers and based on detecting the derivatives of the outputs from the facets to be coated.

In addition, the solder mask coating on printed circuit board, with the plasma treatment, can also obtain certain roughness and high active surface, thus improving the solder coating adhesion.
