Abstract

Bone ablation with 400 ns pulses of a mechanically Q- switched CO₂ laser is reported. A miniature water spray was used, which alleviates tissue carbonization, even at high laser pulse repetition rates, and increases ablation efficiency. An ablation threshold of less than 2 J/cm², an optimal energy density of 10 J/cm², and a corresponding specific ablation energy of 25 - 30 J/mm³ was found for pig thighbone compacta at (lambda) equals 9.57 micrometers , and a beam waist diameter of 0.5 mm.
