The prevalence of tattoos continues to grow as modern society's stigma towards this form of body art shifts towards greater acceptance. Approximately one third of Americans aged 18-25 and 40 % of Americans aged 26-40 are tattooed. As tattoos continue to rise in popularity, so has the demand for an effective method of tattoo removal such as lasers. The various colors of tattoo inks render them ideal targets for specific lasers using the principle of selective photothermolysis. Traditional laser modalities employed for tattoo removal operate on pulse durations in the nanosecond domain. However, this pulse duration range is still too long to effectively break ink into small enough particles. Picosecond (10) lasers have emerged at the forefront of laser tattoo removal due to their shorter pulse lengths, leading to quicker heating of the target chromophores, and consequently, more effective tattoo clearance. Recent studies have cited more effective treatment outcomes using picosecond lasers. Future comparative studies between picosecond lasers of various settings are necessary to determine optimal laser parameters for tattoo clearance.
随着现代社会对这种人体艺术形式的 stigma 转向更大程度的接受，纹身的流行率持续上升。年龄在 18 - 25 岁的美国人中约三分之一以及 26 - 40 岁的美国人中 40% 都有纹身。随着纹身越来越受欢迎，对诸如激光之类的有效去除纹身方法的需求也在增加。纹身墨水的各种颜色使其成为利用选择性光热解原理的特定激光的理想目标。用于去除纹身的传统激光模式在纳秒域的脉冲持续时间上运行。然而，这个脉冲持续时间范围仍然太长，无法有效地将墨水分解成足够小的颗粒。皮秒（10）激光由于其较短的脉冲长度而在激光纹身去除领域处于前沿，这导致目标发色团更快加热，从而实现更有效的纹身清除。最近的研究引用了使用皮秒激光更有效的治疗结果。未来有必要对各种设置的皮秒激光进行比较研究，以确定纹身清除的最佳激光参数。
