Laser-induced plasma ablation-based puncture treatment of cancer

Abstract

This paper investigates a influence of a laser-induced plasma ablation for a tissue. A pulsed laser cause vaporization of tissue by plasma if a laser can provide high-density energy within a very short pulse duration. Such phenomena are called laser-induced plasma ablation. Nanosecond laser output could cause an optical breakdown in the air. To evaluate thermal damage and destruction of tissue in the laser's vaporization, experiments to irradiate tissue were conducted. The experimental results show that nanosecond laser caused vaporization without thermal damage and destruction at the tissue approximant 300 μm away from the ablation area.
