In this paper we describe the results of laser damage threshold studies conducted on silica fibers with etched random anti-reflection surfaces on their end faces. This study includes damage threshold of Motheyed surfaces on witness sample and fibers. Initial work has shown very promising results with damage thresholds greater than 46J/cm2 at 755nm on fibers.
