Percutaneous ablation of degenerative disk material by laser has been introduced recently as an alternative to enzymatic or mechanical discectomy. The optical properties of degenerative disk material were evaluated in the range from 200 to 2200 nm, which includes most of the laser wavelengths used for medical purposes. Remittance rate was determined in 16 post-mortem disks using a spectrophotometric unit and rate of absorption and scatter were calculated. High rates of diffuse remittance were found for classical laser wavelengths such as the argon or the Nd:YAG II laser indicating only low rates of absorption. In contrast, much higher rates of absorption were determined for excimer or mid-infrared lasers as well as for the Nd:YAG I (1320 nm), which appear more appropriate for laser discectomy than the Nd:YAG (1064 nm) laser.
经皮激光消融退变椎间盘组织最近已被引入，作为酶促或机械性椎间盘切除术的替代方法。在200至2200纳米范围内评估了退变椎间盘组织的光学特性，该范围涵盖了大多数用于医疗目的的激光波长。使用分光光度计测定了16个死后椎间盘的透射率，并计算了吸收和散射率。发现氩激光或钕:钇铝石榴石II激光等传统激光波长的漫射透射率很高，表明吸收率很低。相比之下，准分子激光或中红外激光以及钕:钇铝石榴石I（1320纳米）的吸收率要高得多，这些激光似乎比钕:钇铝石榴石（1064纳米）激光更适合用于激光椎间盘切除术。
