Abstract

Two-wave mixing in a Bi₁₂TiO₂₀(BTO) fiberlike crystal at a laser-diode (LD) wavelength of 685 nm is presented. The energy-exchange effect between two coherent beams is observed in BTO single-crystal optical fiber under external alternating voltage. A laser-diode optical-heterodyne interferometry with a photorefractive two-wave mixing in BTO crystal is performed by using a frequency-ramped LD. The photorefractive grating is averaged with the time constant of a crystal. The experimental result is shown to measure a motion of a minor attached to a piezoelectric transducer.
