Abstract
The present disclosure provides a surgical laser system configured to interpolate damage to an optical fiber in which laser energy is transmitted to ablate a target. The surgical laser system is configured to measure, with one or more signal detector, intensity of parasitic reflections from the proximal and distal facets of the optical fiber. Further, the surgical laser system is configured to interpolate damage to the optical fiber based on the measured intensity and to dynamically adjust operation parameters and/or display alerts to a user based on the interpolated damage.
