Bulk periodically poled MgO:LiNbO/sub 3/ with high optical damage resistance

Abstract

Summary form only given. We proposed and demonstrated a novel corona discharge method for the fabrication of bulk periodically poled MgO doped LiNbO/sub 3/ (PPMGLN). We successfully fabricated bulk PPMGLN with a period of 4.7 /spl mu/m for wavelength of 473 nm and 7.0 /spl mu/m for wavelength of 532 nm. Using this PPMGLN we have newly developed blue and green solid-state lasers and they have been used for high-speed color photographic printers in Digital Lab System FRONTIER. It is known that MgO doped LiNbO/sub 3/ (MgO-LN) substrate has high resistance to optical damage. However except for corona discharge method, it is generally difficult to fabricate the bulk PPMGLN. We have made clear of the mechanism of domain inversion of Z-cut MgO-LN.
