1987 DuPont manufactured 4560 denier Kevlar/Epoxy Strands were instrumented with nine and three sensors each. Stress tests were performed at 30,45,60,70 and 80% of ultimate strength with dwell times of 10,000 seconds. FBG showed uneven stress levels

Self-controlled optical-beam steering in nonlinear optical media has been intensively studied over the last three decades. We show that refractive-index decrease on upconverted photobleaching leads to an optical beam splitting into multiple beams (op
