![]() The Future Depends on Optics Edmund Optics101 East Gloucester Pike Barrington, NJ 08007 United States See us at Automate 25 in Detroit (MI), USA, May 12–15 (booth 4400), SPS Italia in Parma, Italy, May 13–15 (hall 5, booth 055) and LASER World of Photonics 2025 in Munich, June 24–27 (booth B1.416)! | ![]() 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 Ti:sapphire and Yb:doped laser pulses. 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. Product-specific web page |
