Brillouin-enhanced four-wave mixing phase conjugator with correction for material, thermal, and birefringence aberrations and passive output control

摘要

Summary form only given. In our arrangement both the seed beam and signal beam are generated by the same Nd:YAG laser oscillator. The seed beam is circularly polarized and contains 100 mJ of energy in 10 ns. The signal beam is split using either a polarized pair or a beam splitter. The two beams each pass through laser amplifiers and are split again into two orthogonal polarizations. All five beams, the seed and four signal beams, are focused into a cell containing a Brillouin medium.
