OPTICAL DIODE EFFECT INDUCED BY USING TWO LASER BEAMS IN Mn DOPED KNSBN CRYSTAL

Two laser beams of wave length 632.8nm encouter in Mn doped KNSBN crystal and induce a optical diode. A maximum ratio of 202 for equivalent transmissivity in two directions of the optical diode is obtained at the input powers of 0.876mW and 0.0914mW respectivly and the ratio shows a tendency to increase further.
