POWER AND BEAM-WIDTH DEPENDENCE OF A BATIO3-CE SELF-PUMPED PHASE CONJUGATOR

Power and beam-width dependences of the performance of self-pumped pha se conjugators using a BaTiO3:Ce crystal have been investigated. The i ncident beam was permitted to enter the crystal by the a-face or the c-face. In both cases, the phase-conjugate reflectivity was observed to vary with the power and beam width of the incident beam. In the for mer case, two different optical beam patterns in the crystal can be ob served under different conditions. Qualitative explanations are given to some of the results observed.
