Opto-optical switching of a 1.06-µm signal beam by another 1.06-µm control beam has been observed in CdTe:In. The switching is caused by the photocharge created by the control beam and the resultant electric-field shielding. This effect can be switched in microseconds and takes advantage of the high figure of merit (n3r/∊) of CdTe.
