目前，激光去除硬组织的能力有限。此外，许多激光系统，如用于消融骨或硬牙齿组织的长脉冲红外激光，也会产生不可接受的热水平，并导致附带的组织损伤。然而，超短脉冲激光是高效、安静且相对无损伤的。随着最近的发展现在允许在高脉冲重复频率下操作，超短脉冲系统可以产生显著的材料体积去除，这可能会赶上甚至超过传统技术，同时仍然保持最小的附带损害特性。在本文中，我们报告了350ps脉冲与硬组织相互作用的初步研究，并将我们的结果与纳秒消融机制进行了比较。
Lasers are currently limited in their ability to remove hard tissue. Furthermore, many laser systems, such as the long pulse infrared lasers used to ablate bone or hard dental tissue, also generate unacceptable heat levels and cause collateral tissue damage. Ultrashort pulse lasers, however, are highly efficient, quiet and relatively free of damage. With recent development now allowing operation at high pulse repetition rates, ultrashort pulse systems can yield significant material volume removal which can potentially match or even exceed conventional technology while still maintaining the minimal collateral damage characteristics. In this paper, we report on preliminary studies of 350 fs pulse interactions with hard tissue and compare our results to the nanosecond ablation regime.
