随著光疗回春概念的演进，雷射机器的设计也朝向大光点、长脉宽（long pulse），再加上表皮冷却系统的利用，可使雷射的能量可以穿透到更深的真皮层刺激胶原蛋白增生，却不致于伤害表皮，同时复原期短，更符合...

对长脉宽脉冲激光弯曲后的硅片试件进行了表面形貌以及晶相等特性分析。
Surface properties such as profile and crystal phase of bent silicon samples by long laser pulses were analyzed.
结果表明，长注入脉宽可以提高内表面注入能量，但对注入剂量影响不大；
The results showed that long pulse could increase impact energy on inner surface but had little effect on retained dose.
