Title:
NONLINEAR OPTICAL CRYSTAL
Document Type and Number:
Japanese Patent JP2693740
Kind Code:
B2
Abstract:
PURPOSE: To provide a nonlinear optical crystal strontium beryllatoborate (SBBO) of the entirely new type, assured of or improved in the advantages of BBO related to SHG.
CONSTITUTION: This strontium beryllatoborate nonlinear optical crystal is strontium beryllatoborate which is a nonlinear optical crystal. The compsn. formula thereof is Sr2Be2B2O7 and its space group is P-63(C66), its point group is C6 and its unit lattice is a=4.663(3)&angst , c=15.332(7)&angst , z=2. The volume of the unit lattice is v=283.3&angst . The crystal belongs to crystals of having a negative optical axis, has hardness of about 7 in Mohs hardness, has a m.p. of 1400°C, is free from deliquescent property in the atm. air and has improved mechanical properties.
