Abstract
A phase-aberrated pump beam was photorefractively coupled to a divergent signal beam in BaTi03 at 514.5 nm. Pump-to-signal ratios were set to induce large modulation depths. No phase cross-talk was observed in the amplified signal beam or in the depleted pump beam. However, phase aberrations present on the pump beam did deleteriously affect energy coupling.Keywords
