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.
