Abstract

For BaTiO₃:Ce to produce bridge mutually-pumped phase conjugation (MPPC), it is not thought to be achievable because the pump beam incident upon crystal's `a'-face can easily result in strong self-pumped phase conjugation (SPPC) in a wide input range. Therefore the more easily a SPPC is undergone; the more difficult a bridge MPPC is made. However we for the first time, to our knowledge, have successfully obtained the bridge MPPC in BaTiO₃:Ce by using two He-Ne laser beams. At some an incident normal angle, there is a transmissivity of as high as 40%. We tentatively suggest the formation mechanism and give a possible explanation of the observed effects.
