A study of the effect of fiber laser at wavelength of 1.08 μm radiation applied to a soft tissue
In this paper, we have investigated the effect of high-intensity laser radiation with a wavelength of 1.08 μm applied to soft biological tissues. We have designed a laser model that has a fiber with a multicomponent cladding of GTWave type and core doped by ytterbium ions, that has been used as an active medium. The maximal power of the fiber laser is 9 W in continuous wave mode. As a result of laser exposure, we have obtained laser craters in muscle tissue and skin. An effective time of action has been chosen (for muscle tissue 60 s, for skin 17 s). The developed laser model can be used for surgical purposes. It is assumed that the highest tissue removal efficiency could be provided by the contact method of exposure.
