Abstract :
We have demonstrated the utility of optical coherence tomography (OCT) as a nondestructive diagnostic tool to evaluate the laser marking performance. The pit formed at different laser marking conditions was imaged by using conventional scanning electron microscope and OCT. OCT images verified feasibility and potential for monitoring of laser processing.
