title: Fanning noise reduction in photorefractive amplifiers using incoherent erasures.
abstract: We propose and demonstrate a new scheme of beam fanning reduction in photorefractive amplifiers by using incoherent erasure. This simple and effective approach employs a pump beam with a mixed polarization state or introduces a third incoherent beam for selective erasure. The approach is analyzed, and the experimental results are presented and discussed.
