23 September 1996Photorefractive Zn-Fe:LiNbO3 crystal for real-time double-exposure interferometry application
Zn, Fe:LiNbO3 crystal, with fine photorefractive properties, has been grown by Czochralski technique. Its response time was measured to be about ten seconds, the diffraction efficiency to be higher than 70 percent. Employing Zn, Fe:LiNbO3 as a holographic record media, another photorefractive crystal Cu:KNSBN as a self-pump phase conjugate mirror, the double-exposure interferometry has been studied in this paper.
