Interstitial laser photocoagulation (ILP) was performed in vitro in lean bovine and chicken muscle by delivering 1.6 W of continuous-wave Nd:YAG laser energy (1064 nm) from a 400-microns core optical fiber for 300s. The resulting thermal coagulation lesion was consistently larger when the delivered energy was deposited into a small steel sphere than when it was delivered freely into the tissue. Mathematical modelling confirms this result. This preliminary study suggests that a point heat source produces a larger volume of thermal coagulation than a point optical source (1064 nm) delivering the same power.
通过一根400微米芯径的光纤传输1.6瓦连续波Nd:YAG激光能量（1064纳米）300秒，在体外对瘦牛和鸡的肌肉进行间质激光光凝（ILP）。当将传输的能量沉积到一个小钢球中时，所产生的热凝损伤始终比将其自由传输到组织中时更大。数学建模证实了这一结果。这项初步研究表明，与传输相同功率的点光源（1064纳米）相比，点热源产生的热凝体积更大。
