Why am I so excited about the new CO2 9.6µm wavelength laser? Because the 9.6µm wavelength is the only wavelength optimally absorbed in hydroxyapatite which appears in all types of hard tissues such as enamel, dentin and bone. When the CO2 9.6µm wavelength laser is absorbed in the hydroxyapatite it causes an explosive vaporization effect which changes the morphology of the hard tissue surface by vaporizing it instantaneously. Although cutting through hard tissue, it may feel like you are cutting through soft tissue.
