In this paper we present a study of laser damage to large core multimode glass optical fibers by high peak laser power of up to 175 kW. Fibers samples prepared with polymer coatings having different refractive indices were tested in a twopoint bend tester while transmitting laser light. The peak power used in the experiment clearly differentiated the performance among the samples. A polymer coa...

industry, medicine and other areas of contemporary life. The essential ingredients of a laser are a material that amplifies light through stimulated emission (the gain medium) and a cavity that traps light in the gain medium to enable more efficient amplification. The gain medium is pumped electrically, by a source current, or optically, by another laser source or a lamp. The most common laser ...
