APPARATUS FOR PRODUCTION OF OPTICAL WAVELENGTH CONVERSION ELEMENT

摘要

PURPOSE:To provide the apparatus for production of the optical wavelength conversion element which can evaluate the orientation bearing and crystalline state of an org. single crystal constituting a core in the process for production of the fiber type optical wavelength conversion element. CONSTITUTION:This apparatus for production of the optical wavelength conversion element produces the fiber type optical wavelength conversion element by growing the org. single crystal having a nonlinear optical effect within a capillary 3. The apparatus has an annular furnace 4 which is inserted and disposed with the capillary 3 and heats the capillary 3 from its outer peripheral surface, a transporting mechanism which moves fowards and back wards the capillary 3 inserted and disposed in this annular furnace 4 in its axial direction and a polarization microscopic Raman scattering spectroscopic system for detecting and identifying the org. single crystal growing in the capillary 3.
