The current work explores the surface morphology of the laser-ablated bone using Yb-fiber coupled Nd:YAG laser (λ = 1064 nm) in continuous wave mode. As the laser-ablated region contains physiochemically modified carbonized and nonstructural region, it becomes unknown material for the body. Thus, biomineralization on such a laser-ablated region was assessed by in vitro immersion test in noncellular simulated body fluid. The presence of hydroxyapatite was detected in the precipitated mineral product using scanning electron microscopy equipped with energy dispersive spectroscopy, and X-ray diffraction analysis. The effect of varying laser parameters on distribution of surface morphology features was identified and its corresponding effect on biomineralization was studied.
钇铝石榴石激光（λ = 1064 nm）对骨进行激光消融后的表面形态。由于激光消融区域包含物理化学性质改变的碳化和非结构区域，它对身体而言成为未知物质。因此，通过在无细胞模拟体液中进行体外浸泡试验来评估在这种激光消融区域上的生物矿化作用。使用配备能量色散光谱的扫描电子显微镜和X射线衍射分析，在沉淀的矿物产物中检测到了羟基磷灰石的存在。确定了不同激光参数对表面形态特征分布的影响，并研究了其对生物矿化的相应影响。
