Abstract

Multimode optical fibers are used for the transmission of high power laser pulses and as phase conjugated mirrors by stimulated Brillouin scattering. Both applications are enhanced by antireflection coatings on the fiber end-faces. Fiber transmissions reach more than 99.5% for pulse energies below the threshold of stimulated Brillouin scattering. Laser-induced damage thresholds of the fibers coated with Ta₂O₅ / SiO₂ were measured at 1064 nm and 24 ns pulse duration. A damage threshold of up to 101 J/cm² could be achieved. The damage morphology was investigated using atomic force microscopy and scanning electron microscopy.
