This study proposes an additional feature of optical coherence tomography (OCT) as a guidance system for laser surgery. aiming to enhance ablation efficiency during laser osteotomy. A long-range Bessel-like beam OCT system is integrated with an Er:YAG laser. The signal sensitivity of the OCT system is measured under various conditions encountered during laser osteotomy. https://www.spidertattooz.com/1969-Ford-Mustang-Black-Metallic-with-Pink-Stripes-and-Wheels-Pink-Slips-Series-1-32-Diecast-Model-Car-by-Jada/
