Paper Abstract

The beam quality of solid-state lasers with high average power can be greatly improved using phase conjugators based on stimulated Brillouin scattering (SBS). The common phase conjugators used until now are liquid or gas cells.Using SBS in glass fibers as phase conjugators the field of applications can be expended. The long interaction length and small cross-sections of the fibers result in an appreciable reduction of SBS threshold and avoid optical breakdown which could happen in liquids and gases at high input energies. Other advantages of glass fiber phase conjugators are harmlessness and easy handling. We have experimentally investigate a phase conjugator base don SBS obtained in an undoped quartz fiber with core diameter of 200 micrometers . The SBS threshold reflectivity and phase conjugation capability were measured with 18 ns pulses at 1.06 micrometers wavelength with different input energies.
