Where to Buy Optical Crystals

Nonlinear crystals of either β-barium borate (BBO) or lithium triborate (LBO) are used for frequency conversion of laser sources. BBO crystals feature thicknesses from 0.2 mm to 0.5 mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of pulses from Ti:sapphire and Yb-doped lasers. The critical and noncritical phase matching LBO crystals are ideal for second or third harmonic generation of Nd:YAG and Yb-doped lasers. Nonlinear crystals with 20–10 surface quality and λ/10 (LBO) or λ/8 (BBO) surface flatness provide the broad transparency range and large nonlinear coefficient needed for the harmonic generation of fundamental laser frequencies. Each crystal features a protective anti-reflection (AR) coating that minimizes reflection and limits fogging from ambient conditions.
