Lithium triborate (LiB3O5) LBO is a non-linear optics crystal. It has a wide transparency range moderately high nonlinear coupling high damage threshold and desirable chemical and mechanical properties. This crystal is often used for second harmonic generation (SHG also known as frequency doubling) of Nd:YAG lasers (1064 nm → 532 nm). LBO can be both critically and non-critically phase-matched.
