LBO crystal is grown with an improved flux method. LBO is an orthorhombic crystal 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. Now, A-STAR provides high-quality LBO crystals
for many applications.

LBO Features:
1. Broad transparency range from 160 nm to 2600 nm (SHG range from 550 nm to 2600 nm).
2. Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
3. Relatively large effective SHG coefficient (about three times larger than that of KDP).
4. High damage threshold (18.9 GW/cm2 for a 1.3ns laser at 1054 nm).
5. Wide acceptance angle and small walk-off.
6. High optical quality (homogeneity DN 10-6/cm) and free of inclusion.
