Paper Abstract

We propose a method to perform two-beam coupling, in which the pump beam was incident upon the +c face and formed a curved light path toward the a face. With this special pump arrangement a part of the fanning beam could also play an important role of pumping of the signal beam and the influence of the fanning effect could be minimized. Thus a high two-beam coupling gain as high as 3.27 by 105 has been obtained at the steady state and a several times higher has been observed at the beginning.
