The deposition of hydroxyapatite thin films has become a topic of interest in medical applications. This dental film applied on the surface of the tooth may act as a highly resistant and flexible artificial enamel, protecting teeth and removing tooth sensitivity. Other possibilities include whitening and coating enamel-deficient structures. We obtained this flexible film of hydroxyapatite using laser ablation. The plasma plumes were generated by an Nd Y"G nanosecond laser in a vacuum chamber. We used the pulsed laser deposition PLD technique and conducted investigations using optical emission spectroscopy OES , laser-induced breakdown spectroscopy LI"S , and Raman spectroscopy. Initially, a thin film of H" was deposited on a soluble substrate and heated, followed by immersion into pure water to dissolve the substrates.
