Recently, a novel quantum square pulse (QSP) modality has been added to the range of treatment parameters of variable square pulse (VSP) Er:YAG dental lasers. In this paper, physical mechanisms enabling the QSP technology are reported. One of the major advantages of the QSP mode is that it significantly reduces undesirable effects of laser beam scattering in the debris cloud during hard tissue ablation. The cavities made with the QSP mode are sharp and well defined, and with minimal thermal effects at the edges of the cavities.
