Description

LBO Non-Linear Crystal is a nonlinear optical crystal. It serves frequency doubling (SHG) and tripling (THG) of YAG(Nd), YLF(Nd), and YVO4(Nd) lasers. Its transmission runs 0.21 to 2.3 um. It is a useful nonlinear optical material for ultraviolet and visible lasers. The material is lithium triborate.

LBO Non-Linear Crystal phase matching

Temperature-controllable non-critical phase matching covers 1.0-1.3 um for type I SHG. Room-temperature NCPM serves type II SHG at 0.8-1.1 um. Spectral NCPM sits near 1300 nm. Alignment tolerances relax. Temperature tuning replaces angle tuning. NCPM eliminates walk-off in the phase-match direction. NCPM simplifies oven control design for stable long-term operation.

LBO Non-Linear Crystal advantages

Broad transparency from 160 nm to 2.6 um. High optical homogeneity (Δn ~10⁻⁶/cm), free of inclusions. Relatively large effective SHG coefficient, about three times KDP. Wide acceptance angle with small walk-off. Type I and type II NCPM across a wide wavelength range. High damage threshold. The 3x KDP coefficient keeps conversion efficient. Homogeneity keeps beam quality high. Inclusion-free material cuts scatter losses across the full aperture.

Typical applications

Medical and industrial YAG(Nd), Sapphire(Ti), and LiSAF(Cr) lasers. Scientific research and high-power YAG(Nd) and YLF(Nd) lasers. OPO and OPA, SHG and THG for high-power 1340 nm YAP(Nd) lasers. High-power labs standardize on LBO for reliability. 1340 nm YAP systems rely on it for harmonics. One crystal covers medical to industrial lasers reliably.
