Title:
METHOD FOR PREPARING BORATE-BASED CRYSTAL AND LASER OSCILLATION APPARATUS
Document Type and Number:
WIPO Patent Application WO2004079060
Kind Code:
A9
Abstract:
A method for preparing a borate-based crystal which comprises dissolving water-soluble raw materials into water to form an aqueous solution, evaporating the water in the aqueous solution or evaporating the water followed by sintering, to thereby provide a material for raising a crystal, melting the resultant material for raising a crystal, and then growing the borate-based crystal; and a laser oscillation apparatus using a borate-based crystal prepared by the method as an optical element for wavelength conversion. The method allows the preparation of a borate-based crystal being useful as an optical element for wavelength conversion or the like, with a reduced time required for the preparation, at a reduced cost, with ease, with enhanced uniformity in quality and excellent reliability, and the laser oscillation apparatus exhibits enhanced reliability.
