The interaction of laser radiation with the nucleus pulposus from autopsy specimens of human intervertebral disks was evaluated at different wavelengths (193 nm, 488 nm & 514 nm, 1064 nm, 1318 nm, 2150 nm, 2940 nm, and 10600 nm). A significant correlation of linear least squares fit of the mass ablated as a function of incident energy was found for all lasers used except the Excimer at 193 nm. The 2940-nm Erbium:YAG laser was most efficient in terms of mass of disk ablated per joule in the limited lower range where this wavelength was observed. At higher energy levels, the CO2 laser in the pulsed mode was most efficient. However, the Nd:YAG 1064-nm and 1318-nm lasers are currently best suited for percutaneous laser disk decompression because of the availability of usable waveguides. Carbonization of tissue with the more penetrating Nd:YAG 1064-nm laser increases the efficiency of tissue ablation and makes it comparable to the Nd:YAG 1318-nm laser.
在不同波长（193纳米、488纳米和514纳米、1064纳米、1318纳米、2150纳米、2940纳米和10600纳米）下，评估了激光辐射与人类椎间盘尸检标本中髓核的相互作用。除了193纳米的准分子激光外，在所使用的所有激光中，发现消融质量与入射能量的线性最小二乘拟合存在显著相关性。在观察到该波长的有限较低范围内，就每焦耳消融的椎间盘质量而言，2940纳米的铒：钇铝石榴石激光效率最高。在较高能量水平下，脉冲模式的二氧化碳激光效率最高。然而，由于有可用的波导，1064纳米和1318纳米的钕：钇铝石榴石激光目前最适合经皮激光椎间盘减压。穿透力更强的1064纳米钕：钇铝石榴石激光使组织碳化，提高了组织消融效率，使其与1318纳米的钕：钇铝石榴石激光相当。
