ABSTRACT:
A surgical system that ablates soft tissue. The system may include a fiber laser oscillator as the gain medium that emits electromagnetic radiation. The system may process the electromagnetic radiation, and direct the electromagnetic radiation on to the soft tissue to be ablated. Due at least in part to the nature of the electromagnetic radiation emitted by the fiber laser oscillator, the system may provide various enhancements, such as a higher power conversion efficiency, a longer lifetime, less heat dissipation, a more compact design, and/or other enhancements, for example. The system may also generate electromagnetic radiation with a relatively high beam quality. This may reduce beam divergence and beam spot size on targeted soft tissue, thereby enhancing power density in the electromagnetic radiation guided to the soft tissue. This enhanced power density may facilitate effective ablation.
