LBO

 Lithium triborate (LiB3O5 or LBO) is an excellent nonlinear optical crystal. It has widely recognized for these features:

Wide transparency range (210 nm – 2300 nm)
Moderately nonlinear coupling
High damage threshold
Good chemical and mechanical properties
For type I SHG of 1000 nm – 1200 nm possibility of non critical phase matching
Free of gray track effect therefore very useful in green lasers
LBO has non-critical phase matching conditions (NCFM) for Type I SHG at 1000-1300nm. In this case, LBO is free of walk-off limitations and, therefore, long LBO crystals can be used. LBO crystals are free of the grey track effect and as a result, are very useful in high power green lasers.
