LBO is an orthorhombic cyrstal and belongs to the point group mm2. It is built up of a continuous network of B3O7 groups with lithium cations locating in the interstices. The compact network of B3O7 groups makes the LBO crystal almost free of inclusion.
LBO Features:
-
Broad transparency range from 160nm to 2600nm (SHG range from 550nm to 2600nm).
-
Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
-
Relatively large effective SHG coefficient (about three times larger than that of KDP).
-
High damage threshold (18.9 GW/cm2 for a 1.3ns laser at 1054nm).
-
Wide acceptance angle and small walk-off.
-
High optical quality (homogeneity Dn=10-6/cm) and free of inclusion.
